A quick way to lose your witness and be labeled as a hypocrite is to become known as a judgmental person. Jesus speaks to this behavior giving a simple command and a constructive change in focus. While Jesus' disciples are not blind to wrong behavior and wrong beliefs, their first focus is on their own behavior, rather than others'. Only when they've taken the time to get their own behavior right can they offer help to others. Jesus' idea is simple. It's one we need to learn to live by.
