A long time ago, I took a walk down a street in Harlem in New York City. I came upon a man who asked me for a dollar. He had asked a few other people before me, but they only passed him by without glancing his way. I stopped and handed the man some money. As I began to turn away, he reached out and shook my hand. He looked me in the eyes and said, "I will bless you." Now, I'm not saying that was God Himself. But how do we know that it wasn't someone working for him, walking around in disguise, just to see what we would do?
