The Way I see it

"Judging others makes us blind, whereas love is illuminating. By judging others we blind ourselves to our own evil and to the grace which others are just as entitled to as we are."

"If when we judged others, our real motive was to destroy evil, we should look for evil where it is certain to be found, and that is in our own hearts. But if we are on the look-out for evil in others, our real motive is obviously to justify ourselves, for we are seeking to escape punishment for our own sins by passing judgement on others"

- Dietrich Bonhoeffer in The Cost of Discipleship p.185
