Condemnation always involves some degree of self-righteousness and of distancing ourselves from the one we are condemning. And self-righteousness always involves an element of comparison and of condemnation. Jesus spoke to “some who were relying upon themselves for their rightness and were despising others” (Luke 18:9).
The combination is not accidental. Contempt is a major part of condemnation in the usual case, and when we drop contempt from our soul and our bearing, condemnation rarely occurs, and never with its most devastating effects.”
