Several years ago it was my privilege to be a part of Billy Graham's Congress on Evangelism in Amsterdam, in the Netherlands. After several days packed with these challenging sessions, the 10,000 evangelists there spent one entire afternoon in what was called a Day of Witness. We were given these box lunches and sent across Holland that day to do evangelism in scores of places. And I was asked to be the bus captain for our 40 or so evangelists. Now when I mentioned those lunches to Richard, our bus driver, he was not a happy camper. He didn't seem particularly sympathetic with what we were going out to do - and he sure wasn't going to allow those lunches on his bus. He said, I always end up cleaning up a busful of garbage. The only way we ever got out of the parking lot that day was that I pledged to clean the bus myself.
