I, too, had a similar experience. It was about 15 years ago. I was visiting Underground Atlanta in the daytime with a Jewish friend. We were outside the entrance when a thin, elderly, black male approached us and asked for something to eat. He said he had not eaten that day. I left him with my friend and went down into Underground to get him something to eat. When I can back, he wolfed the food down so fast, I was afraid he would get sick. My friend later told me that he had paced the whole time I was gone. I told my Jewish friend that I had done what a Christian is supposed to do by feeding the man. I had been praying for God to give me the right time to witness to her and it came that evening. We were eating in a restaurant and she asked me why I believed in Jesus. I went to the Old Testament and stated some of the prophecies about the messiah there. Then I told her how Jesus had fulfilled all those prophecies and more. I gave her the good news of Christ and she listened to me. She didn't accept Christ that day and I didn't push it. But I believe I planted seed and that God will make it grow. I will see her in heaven one day. And it was all because of a little "grizzled" black man who needed something to eat. God is amazing. Libby
