Acts 2 is considered one of the greatest sermons of all time, and if you really think about it Peter does a great job sharing the gospel of Jesus. He not only talks about the resurrection, but he even references Joel and David, which are prophesies about Jesus.
In this chapter we see the fulfillment of the Holy Spirit come, and we see many people added to the church. If you ever have questions about the purpose of church read the book of Acts because they are a perfect representation of God's church!
