Peter spoke, full of the Holy Spirit. The audience took note they had been with Jesus! Cool! I hope people can notice that about me by the way I talk. I think it was because of the way they used the Scriptures. While Peter and John were heading to the slammer, 5000 people responded to the message!
Peter spoke to the same crowd with the same prominent names that crucified Jesus. They are not friends. Their interrogation began with the question, "How did you do this?" Peter told them, by the name of Jesus who is the only way of salvation.
