The Glory of God in the Gospel
Paul's change of life and purpose was so sudden than even critics can't explain it. His intellect was profound but there is a knowledge that was unknown; knowledge of Jesus' glory. He is glorious in His essence, in His mercy and in His wrath. He is the revelation of the glory of God in time and history. It is a glory that is seen by faith. We see something but there is so much more to see as faith grows.
