As Peter preaches about resurrection, the Sadducees, who don't believe in resurrection, show up annoyed. They arrest Peter and John, throwing them in jail overnight because it's too late for a trial. What bothers the religious leaders isn't the healing but the teaching that Jesus rose from the dead, threatening their theological system and power structure. Yet even opposition can't stop God's mission: about five thousand men come to faith, meaning the church has exploded from three thousand at Pentecost to around eight thousand in just weeks. The apostles land in prison, but the word spreads like wildfire. This pattern becomes the rhythm of Acts, proclaim Jesus, face resistance, watch God multiply the harvest anyway. Opposition reveals what we really believe about God's sovereignty.
