I'm reading Purpose-Driven Life and learned that in all things we should do it for the glory of God. I've learned it before, but I'm learning it again. When I attend a Sunday worship service, I sometimes think about what I can get out of it, and if I didn't get anything out of it, I think man, I should have just stayed home. But the book was saying that we worship to benefit God. To glorify God. We attend Sunday service to glorify God. Not to get something out of it. I mean, it's a nice side effect, but it's not the primary reason. That's so deep. I live my life so selfishly that I'm having a hard time grasping this concept.
