1. Let Christ bear the scrutiny for you!
The perfect man has gone to the cross for you and all the impossible standards that you could never live up to. He met all those ridiculous standards that some people hold you to, and that you even hold to yourself. He has met them all. The most righteous, humble, holy, reverent, human, invested, courageous, prayerful, bold, meek, and kind man that has ever lived. He will bear your scrutiny! Let Him! give to him the impossible scrutiny that you could never fulfill, and that He will always fulfill.
2. Find someone to share this scrutiny with
For me it happened to be a regular meeting with an older, wiser man, some really great colleague youth pastors, my very cool German intern, and my wife, but she is the last line of defense because I want to try to protect her and you should too. It is hard to hear negativity all the time though so, "bear one another's burdens and so fulfill the law of Christ". Don't be a one way street. Hear as well as being heard. And then Pray for each other, and you will do well.
3. Pray about it often
If I ever made a mistake in this area it was not praying about it enough. I always would talk to people, gripe, complain, or just get bitter, but I never prayed about it enough. I could have always done that better. Not just, "casting your cares upon Him because he cares for you," but "Pray for your enemies and those who spitefully use you."
Brothers the challenge is always that we are not professionals. We do this out of a deep calling and that calling must come under deep scrutiny because the bible also scrutinizes us. "Let not many of you be teachers because teachers shall incur stricter judgement." This is the tough balance. My greatest prayer for our profession/calling is that we will receive the great judgement from our Lord "Well done good and faithful servant."
