What did Saul preach in the synagogue right after his conversion?
Right after his conversion in Damascus, Saul entered the synagogue and preached that Jesus is the Son of God. He did not preach Christ crucified. This emphasis on His divine Sonship marked a distinct message from the crucifixion-centered preaching. That was the difference.
Les teaches that after Saul's conversion in Damascus, he went into the synagogue and preached that Jesus is the Son of God, not Christ crucified. Les contrasts this with earlier confessions—Peter, Martha, and the Ethiopian eunuch all affirmed Jesus as the Christ, the Son of the living God—but Saul's message emphasized His divine Sonship. Les says, 'See the difference? Oh, it's all the difference in the world.'
