A TV commercial begins with a boy sitting in a play tree house, taunting a grandma and a baby because he has the family’s bag of Doritos chips, and they don’t. The grandma and the baby conspire to get their share. Cooperating with one another, the grandma slingshots the baby to grab the Doritos. It’s a funny illustration of what’s inside all of our hearts—the desire for justice. Unfortunately, our desire for justice is often illegitimate and mixed with revenge, anger, pride, and very little room for God to work.
