"Acts 3-4:4 "

In Acts 1 Christ promise His disciples the Holy Spirit to guide them while He was up in heaven, and He gives them the Great Commission while He ascended into heaven. But they had to wait for the Holy Spirit before they start the Great Commission, and in Acts 2 they received the power of the Holy Spirit on the day of Pentecost. In that chapter we read the Great Commission operating on all 4 cylinders throughout Peter's first sermon that saw the church adding  3,000 souls.

In Acts 3 and 4 we read about Peter and John at the temple, doing the first apostolic miracle, Peter's 2nd sermon that led to 5,000 more souls being saved, and also being persecuted by the Sandherin that could not charge them with anything. So from Acts 2 through 4 the Great Commission goes from the public setting to outside the temple, than to the Sandhedrin Counsel for them to be persecuted. That fulfills Christ's prophecy to when He claimed they will be persecuted, and that the Spirit will speak for them.

Acts 3
verses 1-11, First Apostolic Miracle
We read in verse 1 that even though apostle are saved they still keep their Jewish tradition, cause at the 9th hour of the day they went up to the temple to pray. That temple became the setting for their first Apostolic Miracle, and it brought more people to them for Peter to preach his second sermon.
The first Apostolic miracle had to do with a man that lame since birth, and it was 40 years before he can walk. That lame man was carried to temple gates called Beautiful, and he would lay there asking for alms. He asked Peter and John who were about to go into the temple for alms.
Peter told him gold, and silver I do not have, but Peter called on the name of Jesus to heal him. That lame man leaped for joy to praise God, and that brought people to Peter and John. This set up Peter's 2nd sermon.

verses 12-26, Peter's 2nd sermon
In Peter's 2nd sermon He preached on the connection between Abraham and Jesus. This crowd that ran to them was predominately Jewish, because they were at, or near the temple. Peter told the crowd that Jesus was the promise one that God promised Abraham, and he was the one Moses prophecy about when said there will be a prophet like him. Like in his first sermon Peter mentions two predominant historical figures of Israel, and he used them to show the connection they had with Christ. Christ was the promise Messiah that they delivered to Pilate that was about to let Him go, but they denied the Holy one by having Him take place of a murder. That led to Christ's crucifixion, and God raised Him from the dead to where Peter claimed they were witnesses to.
Peter tells the crowd that it was in Christ's name that this man was healed, and Christ's suffering at the cross was to fulfill God's prophecy to the prophets. Peter's message preached on Christ being the messiah, cause he was telling the crowd this was meant by God to reveal His promise to them. Again the prophet Joel states in the last days His Spirit will dwell among His people to show wonders, and people saw that with lame man being , and that set Peter's message to set up the Great Commission.
In verse 19 Peter tells them to repent of their sins to be converted to receive the promise that God promised Abraham, so they can have the covenant in a resurrected savior Jesus. He's one that could bless them in turning away from their iniquities.

Acts 4:1-4, The First Persecution
As Peter and John spoke they grabbed them to put them in hold until the next day. They that grabbed them are the priest, captain of the temple, and the Sadducees came upon them. They were grieved that they preached Christ's resurrections, because Peter's message of Christ convicted them to. They reacted differently, because their pride would not allow them to repent. This ends up them trying to accuse Peter, and John for doing something that is not illegal. People that day who heard the word got saved, and it was about 5,000.

Recap of Acts 3 and Acts 4:1-4
We read the Holy Spirit healing a lame man that could not walk since birth, preaching through Peter on the resurrected Savior that led 5,000 people to repentance, and also we see the wolves attacking the church. Yet with the church surrounded by wolves it still grew, cause it was running on all 4 cylinders of the Great Commission. They were doing Jesus' method.
