Judge me, O Lord; for I have walked in mine integrity: I have trusted also in the Lord; therefore I shall not slide. 
 Examine me, O Lord, and prove me; try my reins and my heart. 
 For thy loving kindness is before mine eyes: and I have walked in thy truth. 
 I have not sat with vain persons, neither will I go in with dissemblers. 
 I have hated the congregation of evil doers; and will not sit with the wicked.

It isn't enough to be a good person yourself, your friends and the people and organizations you support should be good also, or at least not evil.
