Jesus does not mean that we should never make judgments. Obviously, we make judgments every day. We judge between right and wrong, dangerous choices from safe ones, etc. Jesus is cautioning us not to judge others in a self-righteous, hypocritical way. We shouldn’t be habitually critical of someone when our own sin needs correcting as well. By judging others in an unbiblical and hypocritical way, we pay an enormous price. Ridiculing others exposes us to the righteous judgment of God, and most of us are not really aware that we bring more suffering on ourselves by our complaints against one another. Judging and accusing is what Satan does.
