In Acts chapter 1 Jesus promises his followers that they would receive power from the Holy Spirit, and the rest of Acts documents what God can do with Spirit-filled followers. In chapter 4 two of Jesus’ closest followers, Peter and John, are brought before the spiritual leaders. And these guys can’t figure out why these followers of Jesus are making such a difference. They didn’t have the right theological training or religious credentials. The spiritual leaders are scratching their heads trying to figure out how such ordinary men are doing such extraordinary things. So they questioned them.
