We’ve all heard it said that “people don’t really change”. Well try telling that to the apostle Paul! What could possibly convince a man who had devoted his life to “persecut[ing] the church of God violently” (Gal 1:13) to then re-dedicate his life to “preaching the faith he once tried to destroy” (1:23)? Only one thing, according to Paul: “a revelation of Jesus Christ” (1:12). If sinners like us have any hope of being changed… redeemed… SAVED… we must be “called by [God’s] grace” (1:15). How does God do this? Why does He do it? In this text, Paul unpacks the origin, objective, and outcome of God’s calling on our lives.
