Truly. Some become the best Pastors, teachers, parents and professionals, good people, good neighbors and the dearest of friends.
Their is only one who is perfect...Jesus Christ, the sinless Son of God the Father. He is THE Judge and has never needed any helpers to judge others.
Those words of wisdom are applicable for those who do the work. Not all find value into changing their behavior. Not to appease others but make our society better because they bring a healthy and purposeful contribution
