Not Just Sundays

Maker of joy, Giver of life. How could anyone who believes in You be sad and think of themselves? God, how could I, knowing Your happiness and majesty, be down? How could I let myself get like this, thinking only of me? There's the answer, I. I have tried unsuccesfully in my own strength to fill the void with things other than You. Even while I try to serve You. Maybe it's because I'm trying to help You along, maybe it's because I don't trust You like I say that I do. God, please help me to walk my faith everyday of the week; not just Sundays.
