That statement makes me examine myself. I have to ask myself, "Am I doing all I can to avoid bringing shame to the Lord or myself? Am I giving my best?"
Doing my best means that I am giving God my FIRST...not leftovers.
I've been tempted to just place things in cruise control and follow the path of least resistance. To turn my head and look away from an issue rather than deal with it. To avoid conflict so that I don't hurt someones feelings.
However, if I'm going to lead, and lead WELL, then I must give God my best in every area of my life.
