Tim Keller has some useful insights into handling criticism.
First, you should look to see if there is a kernel of truth in even the most exaggerated and unfair broadsides. There is usually such a kernel when the criticism comes from friends, and there is often such truth when the disapproval comes from people who actually know you. So even if the censure is partly or even largely mistaken, look for what you may indeed have done wrong. Perhaps you simply acted or spoke in a way that was not circumspect. Maybe the critic is partly right for the wrong reasons. Nevertheless, identify your own shortcomings, repent in your own heart before the Lord for what you can, and let that humble you. It will then be possible to learn from the criticism and stay gracious to the critic even if you have to disagree with what he or she has said.
