During the 2008 presidential race, John McCain was asked by Time magazine to share his "personal journey of faith." In his article McCain shared a powerful story of something that occurred while he was a prisoner of war in Vietnam:

When I was a prisoner of war in Vietnam…my captors would tie my arms behind my back and then loop the rope around my neck and ankles so that my head was pulled down between my knees. I was often left like that throughout the night. One night a guard came into my cell. He put his finger to his lips signaling for me to be quiet and then loosened my ropes to relieve my pain. The next morning, when his shift ended, the guard returned and retightened the ropes, never saying a word to me.

A month or so later, on Christmas Day, I was standing in the dirt courtyard when I saw that same guard approach me. He walked up and stood silently next to me, not looking or smiling at me. Then he used his sandaled foot to draw a cross in the dirt. We stood wordlessly looking at the cross, remembering the true light of Christmas, even in the darkness of a Vietnamese prison camp.
