A friend recently commented about how "real" the Incarnation and Crucifixion could have been.
"If Jesus was truly God and truly Man, then wasn't it like a kid leaving home, but taking Daddy's credit card?" he asked.
To me, the phrase, "truly God and truly Man" means that, in the Incarnation, God became an ordinary human being, just like the rest of us. No Divine Credit Card included. Jesus would have been able to buy his way out of the Crucifixion, if he had that. It was all as real for him as it is for you and me.
All of which strikes me as capturing a major difference between Islam on one hand, and Judaism and Christianity on the other. In Islam, all the Prophets got the Credit Card, in order to maintain the Dignity of God. In Judaism and Christianity, all the Prophets got was a message to deliver, and the barest of instructions. They did what was asked of them, often at great cost to themselves, to show their Devotion to God.
