We judge a person's actions, not the person himself.
Can we judge a person actions without that affecting that person? Can we separate a persons actions from that person and act upon a judgment successfully?
Can we look at it this way...a "judgment" is a response to a persons behavior. Behavior changes...should then "judgment" change and how often should this be practiced as a person struggles with changing behavior?
Is there a difference between judging actions and discerning the spirit?
