That critical spirit has a way of boomeranging. What Jesus is calling us to abandon is that c ondemning of others that knifes into vulnerable areas at the core of their being. That's why it hurts them so much. And that's why we use these weapons so much. We need to work on the anger problem first.
Anger makes the road to condemnation a quick and easy trip.
Fueled by anger, our condemnation and blaming and criticizing can become VERY effective because if we do them well, they continue working even after we stop. This is especially true of children and those who look up to us. When we criticize them, they feel a failure for who they are and wish to be someone else, which of course, they cannot, so the shame continues. Perhaps now you see why half the battle is won once we have learned to give up anger and contempt. When we drop these weapons from our arsenal, condemnation rarely occurs, and never with its most devastating effects.
