There is nothing about not believing in god that keeps you from enjoying the beautiful things created as a celebration of its existance.Consider:
I hate organized religion (the jury's still out on the utility of belief — I can't, but if somebody else wants to, that's OK) but I think many churches are magnificant.
I love gospel music — both old-timey white gospel and especially Af/Am gospel. And I love to sing them — they're tuneful and can "feel" as good as any music I know.
But, apart from my personal preferances, just think of it from a singer's (read "performer's") point of view. Does a good actor have to kill his daughters to play a convincing King Lear?
cheers,
