But Saul increased all the more in strength, and confounded the Jews who lived in Damascus by proving that Jesus was the Christ.
And in this way Saul the persecutor of the church proved that the Holy Spirit had regenerated him, becoming Saul the passionate evangelist for the church. What a powerful, forceful gospel witness was now at work in the church! The leaders of the Jews that were opposed to the growing Christian movement (a group Saul had once led) could not silence a former colleague! In fact, he was so compelling and such a convincing apologist that they were left without answers to his strong message.
It is fun to read this account as Luke writes it. God can turn His enemy into His strong tool! Saul/Paul was always controversial, leaving havoc and mayhem in his wake. He did so before conversion when he hated the church. He does so now in the passage as a passionate follower of Jesus who wants to convince even his fellow persecutors to join him in his new found life in Christ. He is fearless and hard to stop! That's because God can't be stopped.
