Attention! This is chapter 4 of Acts, and it's a doozy. All of the folks in Jerusalem are talking about the healing of this lame dude. Peter and John are the ones who did it, and everyone's in awe of their power! So the Sadducees, who are the religious leaders, are like 'hold up, who gave you the power to do this?' Peter and John are like 'it's the name of Jesus that healed him' and everyone's freaked out. Then Peter and John get thrown in prison, but the people still believe in Jesus and they're praying for them. God sends an angel to free them, so they go back to their friends and start preaching the message of Jesus. BOOM! That's what happens in this chapter.
