Good morning, Grace. It's good to get to spend Sunday mornings with you, even if it is in this way. I hope that you're getting a chance to watch on Sunday morning or sometime throughout the week. Last week, we started in a new series called Still the Church, where we're walking through the book of Acts together. We thought it would be appropriate because it's a time of uncertainty for our church and for the church. In this time of isolation and doing this communal thing by ourselves, it's a difficult time to be the church. It's a difficult time to know how to express the church. And for grace, it's a difficult time to know how to express grace. And so I thought it would be good to go back to our roots, to go back to the foundational beliefs and philosophies and practices of the early church and see what we can learn from the birth of the church in Acts to apply to our church now. Because the same church that is born in the book of Acts is the church that we are now, which is why we are still the church. And that's why we've called this series Still the Church. This week, I want us to look in Acts chapter 2. So if you have a Bible, you can go ahead and turn there. There's a lot of significant things that happen in Acts chapter 2. Actually, we're going to spend two weeks in this chapter looking this week at the foundational repentance and confession of the church, and next week, some of the foundational practices and characteristics of the church. But to understand what's happening here in Acts chapter 2, I think we have to flash back to Luke chapter 23. You'll remember last week that we talked about Acts is really, Acts and Luke are two parts of the same work. They're both addressed to a guy named Theophilus to explain first in Luke's gospel, Jesus and his life. And then the book of Acts is written to tell the story of the early church and is known either as the Acts of the Apostles or the Acts of the Holy Spirit, depending on your translation, but both are appropriate. So to understand what's happening in Acts 2, we need to look at what Luke, the author, wrote in his gospel in Luke chapter 23. In Luke chapter 23, we arrive at this scene where Jesus is in the care of a man named Pontius Pilate. At the time of Christ, Israel was a far-flung province of the Roman Empire. And Pilate was the Roman governor that was put in authority over Israel. And the leaders in Israel wanted to kill Jesus. The problem was, under Roman rule, they didn't have the authority to execute the death penalty. So they had to convince the Romans to do it for them. They had to take their prisoner to the Roman governor, to Pilate in this case, and convince Pilate that this man, Jesus, was worthy of the death penalty. So Pilate's talking to Jesus and he finds no fault in him. He finds no fault in his story. Pilate's wife is even wise and told him, you need to have nothing to do with this man. So Pilate goes to the crowds. There's a crowd gathered outside his fortress, outside his headquarters where he is. And the crowd is a Jewish crowd and they're clamoring for the death of Christ. And there's such a big crowd in Jerusalem at the time because it was the high holidays. It was Passover weekend. So they were there from all the corners of Israel to celebrate Passover. And they had worked themselves into a frenzy pursuing the death of this man named Jesus of Nazareth. And Pilate goes to them. And because he finds no fault in Jesus, he goes to them and he says, hey, I find no fault in this man. It's your tradition to let a prisoner go for Passover. It was the habit that they were in. They let a prisoner go every Passover. And so Pilate says, why don't you invoke that tradition and let this man named Jesus go? He does not deserve to die. And the crowds refuse. And they say, no, give us Barabbas. Barabbas was a known criminal and rebel. And he was in the stockades and was going to be crucified as well. And they said, no, we want to give the free pass to Barabbas. Give us Barabbas and crucify Jesus. And Pilate says, I really don't think that's right. I really don't think that's fair. I wash my hands of this and we pick it up in Luke 23 as they go back and forth. Luke 23, 23 says this, So Pilate decided that their demand should be granted. He released the man who had been thrown into prison for insurrection and murder. That's Barabbas. For whom they asked, but he delivered Jesus over to their will. In another gospel account, Pilate says, It's this profound passage. So from there, Jesus is crucified. He's put in the tomb. The disciples sit there on Friday night, Saturday and Sunday, just kind of wondering what to do and where to go from there. And then on Sunday morning, Mary Magdalene sees the empty tomb and tells the disciples. And shortly after that, Jesus, a resurrected Jesus, appears to the disciples and gives them newfound faith. And he walks with them for 40 days until the day of Pentecost. If you were with us this last fall, we went through these Jewish holidays and you know that Pentecost follows 40 days after Passover. And so Jesus was following the calendar that his heavenly father, that God the father instilled into the Jewish people. It's really remarkable the parallels here. And then 40 days afterwards, he goes up into heaven. Jesus ascends into heaven. He gives the disciples the marching orders. Yours is the kingdom to build. Go into all the world, preach the gospel, make disciples, baptize them in my name, he says. And the disciples are tasked with building the church. And Jesus also tells them, wait until you receive the helper. Wait until you receive the gift of the spirit, because that Spirit is what's going to empower you to build the church. He's actually referring to what he told them back in John. In the book of John, Jesus tells the disciples, it's better for you that I would leave, because when I go, the helper is going to come and he's going to empower you. And so now they're told in Acts, wait for the helper, just sit and wait. So the disciples go back to this upper room and they just kind of sit and stare at each other and wait. I wonder what those days were like. I wonder how they looked at each other and what they were expecting and what they thought the Holy Spirit would be like. And meanwhile, the crowds are still there. They're back for Pentecost. They're back for the holy holiday and they're there. And they know that they crucified this Jesus and now they know that he was resurrected and walking among them for 40 days and that his disciples, his followers are holed up in this room trying to figure out what to do. So the crowds began to clamor around this home to see what the disciples were going to say. And as they're in this room, Acts chapter 2 tells us that the Holy Spirit descended on them like flaming tongues of fire. I can't imagine what that moment must have been like. But the Holy Spirit descends on them like these flaming tongues of fire, and at the reception of the Holy Spirit, they walk out on the balcony and they preach to the crowds. And it's remarkable because they preached in their native tongue, but everyone there heard in their own language. It's the first time in Scripture we see the gift of tongues. That's where we get the idea of the gift of tongues for those of you that are interested in that. And you know, as an aside, Acts really formally introduces us to the Holy Spirit. And Acts brings up a lot of questions about the Holy Spirit. How does the Holy Spirit work? What is the Holy Spirit's job? How do we interact with the Spirit? What does it mean to receive the Spirit? What does it mean to be full of the Spirit? But you know, we also did a whole series on the Holy Spirit last spring. So if you weren't here for that, or you forget that and need a refresher, you can find that series. It's called Forgotten God. It's on our website. You can go back, and we did four weeks on the Holy Spirit, talking about how we interact with him and how he interacts with us and what it means to be full of the Spirit and be empowered by the Spirit. If you want to do even more learning on that, because we're going to focus on something else in this chapter, but if this is something that you want to pursue personally, I would encourage you to read The Forgotten God by Francis Chan. It's the book that we went through last spring. If you haven't heard of it or had a chance to read it, it's a really good introductory book to the Spirit, to His role and to what He does. If you want a little bit more than that, if you have specific questions about what does it mean to be full of the Spirit? What does it mean to be baptized in the Spirit? What does it mean to be empowered by the Spirit? There's a great short read that I have found to be the most helpful book on the Holy Spirit in my experience. It's called Baptism and Fullness by a guy named John Stott. I have one copy of it. The first person to ask me to borrow it is more than welcome to do that. Otherwise, you can find it just about anywhere. If that interests you, that's a super helpful book on the Holy Spirit. But the Holy Spirit descends on the disciples. They walk out on the porch and they preach the gospel. They tell the story of Jesus and who he was. And the crowds they're preaching to, it's important to note, is the same crowd that was clamoring for the death of Christ before Pilate. The crowds they're talking to in Acts chapter 2 is the same crowd, the same community with the same sensibilities that was at the gates of Pilate's fortress clamoring for the death of Christ. This crowd crucified Jesus. And now Peter and the disciples are preaching to them. And what they're preaching to them is, hey, that man that you killed, that resurrected, that we all saw go into heaven the other day, that was the Messiah. That was the promised Messiah that our God had sent. And you killed him. And to do this, to help them see this, it's important that we note that he quotes Old Testament prophets, Peter does. He quotes Joel. There's a huge passage, a huge portion of Acts chapter two that's a quote from the prophet Joel that he's quoting back to them so that they would see, hey, this guy that you killed, he actually fulfilled this prophecy that you know and cling to. This guy that you killed, he fulfilled the prophecy of David that you know and you cling to. And when he finishes, when he finishes, he finishes like this. And the response of the people is incredible. Look at what he says. As they wrap up their sermon, Peter says, It's the same crowd. I love their response. Now, when they heard this, they were cut to the heart and said to Peter and the rest of the apostles, brothers, what shall we do? And listen to Peter's response. This response is incredibly profound. It's a hinge point in history. And Peter said to them, repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. So Peter and the apostles preached to this crowd that crucified Christ. And what they preached to them is, this guy that you killed was the Messiah that was sent from God. It's the Messiah that you've been waiting for generation after generation after generation. It's the one that your grandparents told you about and the one that you've told your children and your grandchildren about. And now he's arrived and you've killed him. And it says that they were cut to the heart. And they said, brothers, what do we do? You're right. We messed up. What do we do? What they're asking in that moment is how do we make this right? How do we make ourselves right before God? We've sinned before God. We've committed an egregious evil. What can we do to settle it up with God? What do we do? How do we get right with God? In our vernacular, in our context, what they're asking is what do we do to be saved? How do we become Christians? How do we get right with God. In our vernacular, in our context, what they're asking is, what do we do to be saved? How do we become Christians? How do we get right with God? It's the same question we ask when we go, what's the barrier of entry to be okay with God? In terms of the church or the kingdom that God is starting here, what they're saying is, what's required of us to be a part of the church? What does God require to join up, to be in his kingdom? What's the barrier of entry? It's all the same question, and they're asking the same thing that we ask. What do we need to do to be right with God? We messed up. And Peter's response is that they should repent and be baptized. And I think it's worth asking, if Peter wants them to repent, what was the repentance Peter was calling for? What was the repentance that Peter was calling for? To repent of what? I think it's a really important question to look at that when they say, what's the barrier to entry? How do we get right with God? And Peter says, repent. I want to know, repent of what? I think we're tempted to just assume that it means repentance of sins. Repent of your sins and be baptized and you will know Jesus and he will forgive you and you receive the Holy Spirit. But we have to consider who this crowd was. This was a Jewish religious crowd. This was a crowd and we know that they were a religious crowd because they were convicted by the words of the Old Testament. These were not a group of people that were just walking through life as if God didn't exist, not caring at all about his laws. They were, most of them, devout Jews. They were, by all accounts, this crowd was, by all accounts, outwardly righteous. This society, this Jewish society that was contemporary of Christ, there wasn't a lot of atheists and agnostics walking around. There wasn't a bunch of aspiritual people walking around. Everybody had faith. Everybody expressed a faith. Everybody claimed God as their father. Far and away, this crowd of people was an outwardly righteous crowd. Meaning, they had already repented of their sins. They weren't going through life like God's laws didn't matter. In fact, one of the reasons they wanted to kill Jesus is because they felt that he had violated one of God's laws and deserved that death. If you were to tell them that they needed to repent of their sins, they would respond in much the same way that you and I would likely respond if you're a believer this morning. If someone told us that we needed to repent of our sins, I think what we would say is, I mean, yeah, I feel like I have. I know I'm sinful. I know I mess up. I'm trying to do better and repentance is kind of progressive. I'm working on it and through the power of Christ, hopefully I'll continue to move away from those sins, but it's not like I'm walking through life not thinking I'm sinful. I think repentance of sins is too broad to apply to this crowd because many of them, if not all of them, felt like they had already done that. What's more is the impossibility of the command, if it applies to all sins, it's the impossibility to fulfill that command in light of what repentance means. Often, and a lot of you know this, but just so we're on the same page, often we equivocate repentance with confession when they're two different things. To confess something is to agree with someone else that what you did is wrong. In spiritual terms, it's to agree with God about your sin. But to repent, to repent has this implication of walking in the other direction, of being headed in one direction, doing one action, and then not only stopping and confessing that that's the wrong way to go, but then turning and moving in the opposite direction. It's like if you lose your temper with your spouse. And after losing your temper, you're sorry and you feel bad and you go, hey, listen, I'm sorry. I shouldn't have done that. That was my bad. You didn't deserve for me to fly off the handle like that. That's confession. You've agreed with your spouse that you were wrong. But repentance would be not just to apologize for what you did, but then to walk in grace and generosity with your spouse moving forward. To repent of sexual sin isn't just to say, that was wrong, I'm not going to do that anymore. It's to actually turn and walk in purity. You understand? To repent of being a thief or being greedy is not to simply stop being greedy or stop taking what doesn't belong to you, but to walk in generosity to others. It's to stop going one way and move in the opposite direction. And that makes this command, if it means to repent of our sins, particularly impossible because no one can perfectly repent of their sins void of the empowerment of Christ in their life. No one is capable of repenting of our sins to the satisfaction of God because that would mean walking in perfection and we can't do that outside the power of Christ. I would argue that we can't do that this side of eternity. So I don't think that what Peter is saying in Acts chapter 2 is that we should repent of our sins as a blanket general statement. We should, and that's fine, but I think there's a more specific repentance happening here. I think he's speaking right to this crowd that was present at the release of Barabbas and the insistence of the death of Christ. He's speaking to the crowd that says the death of Jesus is on our heads and on our children's heads. He's speaking directly to the crowd that once they realized they had crucified the Christ, the son of the living God, they said that they were cut to the heart. What do we do? And Peter says, repent. And I believe that he is telling them to repent of who they thought Jesus was. Peter is calling them in Acts chapter two, the crowds in Jerusalem, repent and be baptized. Repent of who you thought Jesus was. Peter was calling them to repent of who they thought Jesus was. You used to think he was this. You used to think he was just a prophet. You used to think he was a crazy person. You used to think he was a false teacher. You used to think he was making false claims, but now you know who he is. So confess that you were wrong about that and move in a faith of Christ. And I think it's remarkable the parallels in Peter's life because Peter is asking them to make the same confession and repentance that Peter himself was called to by Jesus. What we'll see, what I want to show you is that this repentance that he was calling for in Acts 2 is the same confession and repentance that Peter himself was called to by Jesus. If you flip your Bible over to Matthew chapter 16, you see this incredible scene where Jesus has the disciples gathered in front of him. And he's asking the disciples, they're in northern Israel and as close to the border as you can get. They're out in the country and he's talking to just his disciples and he's saying to them, who do people say that I am? And they said, some say that you are John the Baptist reincarnated. Some say that you're Elisha. Some say that you're a good teacher. And he says, yes, but who do you say that I am? And Peter says, you are the Christ, the son of the living God. Peter confesses that Jesus is the Christ. Look, verse 15, he said to them, but who do you say I am? Simon Peter replied, you are the Christ, the son of the living God. And Jesus answered him, blessed are you, Simon Barjona, for flesh and blood has not revealed this to you, but my father who is in heaven. And I tell you, you are Peter and on this rock, I will build my church and the gates of hell shall not prevail against it. Jesus says, yeah, but I understand what other people might think. Who do you say that I am? And Peter, the one who is to preach the sermon that begins the church years later, says to him, you're the Christ, the son of the living God. You are exactly who you have claimed to be. And Jesus says, yes. And the spirit has revealed this to you. You didn't figure that out yourself. And on this rock, on the rock of that confession, on the rock of that faith, on the rock of the belief that Jesus is who he says he is, that he is the name that he claims to be, Jesus says, on this rock, I will build my church and the gates of hell shall not prevail against it. Years later, Peter is preaching to a Jewish people that killed Jesus and he tells them who Jesus was and they say, what do we do? We messed up. What do we have to do? And Peter preaches to them the same repentance and confession that he made. And he says, you need to believe that Jesus was who he says he was. You need to confess that you killed the wrong guy and you need to walk in faith and fealty to him. The confession that he's asking the crowds to make is the same confession that he made years ago. And it's the confession on which Jesus says, and that is the one on which I will build my church. This passage is incredibly important because it sets Jesus up as the cornerstone of our faith, as the cornerstone of our church. And this is the confession and repentance from which all other things flow. The foundational belief of the church is that Jesus is exactly who he says he is. Don't you see that to be able to confess that Jesus is exactly who he says he is, that you have to be moved to a saving faith? That if Jesus claims that he is the Lamb of God who comes to take away the sins of the world, that to believe that claim, to believe that Jesus is who he says he is when he says he's the Lamb of God, you have to first admit that you're a sinner in need of a Savior. When Jesus says he is the high priest that advocates for us, you have to first admit that you're in need of a high priest to advocate to God because you forfeited that with your sin. When he says that he is the sacrifice that covers over our sin once and for all, do you understand that we have to believe that our sins need covering? When God says that he views us through and sees the righteousness of Christ covering our sins, we have to confess that we have sins that need covering. This confession and repentance and belief in who Jesus is and believing that he is who he says he is is the foundational and fundamental confession and repentance of the whole church. We cannot confess and believe that Jesus is who he says he is without walking in faith to all of his teachings. We cannot. Our behavior changes when we believe who Jesus is because we trust him when he says that he's the good shepherd. And so we walk in light of that trust, in light of that claim. We trust that when Jesus says, I am the way, the truth, and the life, and no man comes to the Father except through me, we acknowledge that he is exactly who he says he is. The barrier of entry into God's church is to believe what Jesus says about himself. It's to believe that he is who he says he is. The reason that Jewish crowd wasn't a part of the church before this moment is because they had wrong beliefs about who Jesus was. And the very second they believe that Jesus was who he says he was, they become the church. And we find out in Acts 2 that about 3,000 were added to their number that day. And this is the birth of the church. That foundational claim is the birth and genesis of the church. And it is still the same foundational claim that welcomes you into the church. If there is somebody who doesn't know Jesus, who does not yet know Christ as God as their father and Jesus as their savior, it's because they don't yet believe that Jesus is who he says he is. Think back to before you were a Christian. If you have that memory of yourself and of your belief system, wasn't the fundamental issue in your heart that you didn't believe that Jesus was who he said he was? Weren't you making the same error that the Jewish crowd was making and disregarding him as something that he claimed not to be? And that the very thing that brought you into faith and salvation was the gradual understanding and confession and repentance of walking in a faith and in trust that Jesus was who he claimed to be, that he was the Lord of lords and the King of kings, that he's Emmanuel, God with us, that he's the Lamb of God who takes away the sins of the world, and that he's the Lion of Judah who comes to conquer hell with his church. Before you were a believer, you didn't believe those things. And once you became convinced that those things were true, you were all in on faith. Isn't that the barrier of entry for a Muslim? A Muslim person thinks that Jesus is simply a prophet. And for them to become a person of a Christian faith, they would have to do away, they would have to repent of the idea that Jesus was simply a prophet and walk in the truth that he is the Messiah who died for them as well. Isn't this the barrier of entry for an agnostic person who before becoming a Christian would argue that Jesus, if he existed, didn't matter very much? Wouldn't it be, isn't the need to repent of that idea of Jesus and walk in a belief that Jesus was who he says he was? If an atheist is going to come to faith, the very first thing they have to do is repent of their idea that Jesus doesn't exist and that God is not real and walk in a belief that Jesus is who he says he is. And for us church people, if sometimes our walk with God feels a little janky, it feels like we're out of step and we're not in sync. We can't get the traction that we'd like. Isn't it possible that we need to repent of some of the ideas that we have about who Jesus is and trust that he is who he says he is? I think some of us, without saying it, we have this view of Jesus like he's some sort of cosmic hall monitor that's just waiting to get onto us and make our life not fun. Yet Jesus promises and tells us and claims that he is the good shepherd and that he came to give us life to the full. Some of us need to repent of who we think Jesus is, that he's just there to squash our joy and kill our fun and walk in the fullness of pleasure that Jesus offers at the right hand of God. We may with our mouths claim that Jesus is Lord, that he is the king of our hearts, that he reigns in us. But in many of our day-to-day lives, mine most of all, he's not the Lord we are. We don't walk in a belief that he is who he says he is. We don't walk like he's the Lord of our hearts. We don't walk like he's the king of the universe. We walk sometimes as if he's something we can put on a shelf and take down when it's convenient or when there is a need. And what we need to do is confess that we view Jesus as this trinket to put on a shelf and repent and stop doing that and walk in a belief that he is the Lord of the universe, that he is creator God and I am creation and I should live my life in a joyful servanthood to him. This confession that Peter calls for in Acts chapter two, this repentance that he calls for is for the crowds to repent of who they thought Jesus was and to believe that Jesus was exactly who he said he was. And in that repentance, the church is born. And in that same repentance, our faith is born. And that invitation that Peter made 2,000 years ago to repent and be baptized for the forgiveness of sins and the reception of the Holy Spirit is the same invitation he extends to us today. My hope and prayer is that this will drive us deeper into learning about our Savior. That we would be constantly asking the question, Jesus, who do you say you are? What does your word say that you are? Where are the areas of my life where I'm not living in harmony with this, where I don't believe what you say, where I'm not trusting the claims that you make? and I think we should pray that God would help us repent of those things, confess those things, acknowledge where we're thinking wrongly about Jesus and walk in a knowledge, an assurity, and a faith in him that he is who he says he is. This invitation to repentance that Peter gives in Acts chapter two is the same invitation that you and I have right now, every day. We're still the church. That's still the foundational repentance. Let me pray for us. Father, we thank you for your son, Jesus. We thank you that he is the cornerstone of our faith, that everything begins and ends with him, that he is the alpha and the omega. Father, teach us to embrace all the many sides of our Savior, the one that is zealous for us, the one that watches out for us, the one that is the high priest for us, the one that is the good shepherd for us, the one that is the way for us, the one that is the bread and the living water for us. Let us be sustained on our Savior. Father, if any of us lacks faith, pray that you would provide it. If any of us is seeing Jesus inaccurately, help us see him more clearly. If we, like the crowds in Acts, need to repent of who we think Jesus is and walk in a truth of who he claims to be, give us the courage and the vision and the faith to do that. It's in your son's name we pray. Amen.
