Mercy is Falling (to pieces)

I played piano for church today and it went fairly badly. We practised just last night, only had the piano, a bass, and a couple of voices, and did a bunch of songs I've never played before. I had about the expected amount of success. However, I realized something fairly important: God doesn't need me to add to his glory. If I do well and it glorifies him, that's wonderful and good. But if I do badly, it's really no loss to him; he's already sufficient unto himself. The only real loss is if I allow a failure to keep me from contributing in the future. So that's my revelation of the week: if I'm playing for myself, then a mistake is a huge issue because I need all the boosting up I can get. But if I'm playing for my God, a mistake is pretty unimportant. He really doesn't need the boost. None of our offerings are flawless in his eyes; all we can give him are our insignificant, tattered best efforts and the hope that he will take them as the best we can give.
