When Jesus told his disciples that they would be his witnesses in Jerusalem, Judea and Samaria, and to the ends of the earth, it’s hard to imagine that they knew what challenges waited for them. Very shortly after the ascension of Jesus, the church was persecuted and scattered. Christians were literally meeting in a cave in Antioch of Syria (which ended up becoming the sending church for Paul and Barnabas on their missionary journeys).
Peter clearly had in mind preaching to Jewish people. But that idea got flipped on its head when God sent him to Cornelius, a God-fearing Gentile. When more persecution came, James the brother of John was killed with the sword. This alone would have been a devastating blow to the disciples, because James was one of the “inner circle” during Jesus’ ministry.
As if James’ death wasn’t bad enough, Peter was imprisoned. “He (Herod) killed James the brother of John with the sword, and when he saw that it pleased the Jews, he proceeded to arrest Peter also” (Acts 12:2, 3 ESV). We don’t know why Herod kept Peter alive and not James, but clearly Herod was most likely going to put on a show for the Jewish people before killing Peter. Luke records a miraculous escape for Peter, then Peter appears to a group of people praying at Mark’s mother’s house. He told them to “tell these things to James and the brothers,” then he left and went somewhere else.
Peter did not shrink back. Neither did the other disciples. They boldly preached the word of God, because Jesus told them that they would be his witnesses. This is an amazing example of the boldness that we need to have today. The Gospel will go on, but we need to be willing to step up and share it.
