If the death and resurrection of Jesus is the hinge on which the great door of history swung open at last, the conversion of Saul of Tarsus was the moment when all the ancient promises of God gathered themselves up, rolled themselves into a ball and came hurtling through that open door and out into the wide world beyond. The story was so important to Luke that he tells it no fewer than three times—here in Acts 9 and then again from Paul’s own lips in chapters 22 and 26. Everything that Saul said and did from that moment on, and particularly everything that he wrote, flowed from that sudden, shocking seeing of Jesus.
