I can still remember a moving Thanksgiving sermon that my pastor preached when I was just 12 years old. The sermon, entitled, "Who Took the Giving Out of Thanksgiving?", was all about the selfishness of our modern-day society. By the close of the discourse, we were all feeling mighty guilty. So when the preacher invited us all to give toward a special offering to help needy families, even I put my lunch money in the offering.
