"Acts is a video report of how the apostles and disciples shared the Gospel message in every possible setting. What we get is to see how the eyewitnesses shared with the world what happened in the life, ministry, death, and resurrection of Jesus. As we go through all 28 chapters we find that there are 22-recorded events where a Gospel Message is presented.
The FIRST Gospel Presentation is in Acts 2. The time has come, after being called to be a fisherman for eternal souls. After being given on site, hands-on training for three plus years. After being tutored privately, commissioned publicly, and filled with the very Holy Spirit of God, Peter steps up to the microphone to deliver his first sermon.
I'm sure his pulse was throbbing in anticipation, his heart pounding with excitement to at last say what he had been taught, shown, and commanded him, to say. So here it is, here is Gospel Presentation number one in Acts chapter 2. Peter preaches the first sermon after Christ's death, burial, resurrection, and sending the Holy Spirit down to indwell the Church." Read more about the Acts of the Apostles from John Barnett.
