Our Sunday school teacher was a quiet, godly man with a quick wit. Reflecting on one of the verses in our Sunday school lesson, "Abstain from all appearance of evil," he said with a chuckle, "But please don't do as I do--do what I say." He explained with a smile. "I was going to the post office and I spotted a beer can on the sidewalk. I picked it up to throw it away. Turning around suddenly, with the empty beer can clutched in my hand, I proceeded to stumble and trip the whole way up the front steps."
