It depends if you believe in that sort of thing or not. He does perform some crazy miracles healing cancer was miraculous to say the least. If you want to look at The Green Mile compared to the story of Jesus, it might be safe to say there are similar plot points. For example: Coffey is killed for a crime he was innocent of, and the two men on death row with him could correspond to the good thief and the bad thief. But although Coffey is able to heal the sick, he doesn't preach a spiritual message. He heals people because he can, not to show the power of faith or anything like that. Hes basically just a massive legend in literature.
