Saul was the great persecutor of those who followed Jesus, but he meets the resurrected Jesus on the road to Damascus on his way to persecute more followers of Jesus and the course of his life is changed. But it is not just the resurrected Jesus who helps bring Saul to that change. God uses Ananias to help bring Saul to that place of change. This demonstrates that God uses everyday people like us to build His kingdom and do His will and we see what we must be willing to do to be used by God in this way.
