Everybody is a critic, but nobody wants to be judged or condemned. Then why is judgmentalism so rampant, even among Christians? "Thinking the best of other people" is necessary if we wish to grow in love. And kindliness in judgment is nothing less that a sacred duty.
"He who judges his neighbor favorably
will be judged favorably by God."
How easy it is to misjudge and how difficult it is to be impartial in judgment. Our judgment of others is usually "off the mark" because we can't see inside the person, or we don't have access to all the facts, or we are swayed by instinct and unreasoning reactions to people. It is easier to find fault in others than in oneself.
