One of the great stories in the Bible is the transformation of Saul, the Pharisee, from a persecutor of the church to the greatest missionary that history has ever witnessed. Seldom does Paul relate that story in his letters. He doesn’t need to because he usually does that in person when he is planting a church. But on this occasion, as he defends his call and the gospel, he retells a bit of his personal history to underscore the complete metamorphosis that has taken place in his life. In his former life, Paul admits—quite painfully, no doubt—that he tried to destroy this movement. Borrowing language from the prophets, Paul narrates how God unveiled to him the truth about Jesus. At just the right moment, even while Paul was an active enemy, God revealed His Son to Paul and called him to be heaven’s emissary to the nations. Paul immediately stopped his campaign against the church, which was just beginning to emerge from its Jewish roots and spread to the Gentile nations.
