Integrity
Reputation is learned in an hour; your character does not come to light for a year. (William Hershey Davis, seminary professor)
How quickly a reputation can be made—and lost! An otherwise good person can make one big mistake, and his reputation is instantly tarnished. On the other hand, a person can live a very good life, but it takes time before he or she is recognized as a person of integrity. Actually, it sometimes takes a lifetime to establish character.
I know, my God, that you examine our hearts and rejoice when you find integrity there (1 Chronicles 29:17).
