QUOTE : Joseph predicted the Exodus, which meant that he knew his descendants would be enslaved by the pharaoh and then freed by God, was the most powerful expression of optimism—and faith—I had ever encountered. It was also, at that moment, an overpowering challenge that I sensed I could no longer continue to avoid. Would I place such credence in a generations-old promise I never actually heard? Could I meet this standard of commitment—to anything? Would I have such faith? Here, at the end of Genesis, was a stirring new prototype of dedication.
