The best opportunities often come when we might be thinking least about teaching the good news, such as during games or when we’re serving food. Sin tends to show up during these activities, so for years I always passed out snacks with the instruction, “Remember to share.” More recently I’ve changed that to, “Be careful; greed is dangerous.” I think my new line sets a better tone. It’s aware of the heart, not mere behavior. It fits people who know that sin runs deep but that God’s people can resist it—even at the heart level.
