Haven't finished this sermon yet, but this is definitely something I want to write down and remember. The sermon title is "We Are All, pt. 1." The guy was talking about how we live our lives with this attitude like we have some great, hidden reserve of untapped potential, and if we could just tap into it, we could do anything. We think so highly of ourselves, like Peter did when he said that he would never deny Christ, even if he had to die with him. We think we won't fail because we're "better than that." Or we feel disappointed in ourselves when we do fail, because we think we should have been "better than that."
But we're NOT. That's why we need a savior.
So in reality, being disappointed in ourselves is actually a kind of pride. We're not better than that. And try as we might, we can't change ourselves and become better than that. The only way we can ever become holy or good is by drawing near to God. We have to remember how needy and dependent we are, or we'll let go of the only One who can help us.
One more point from the sermon that I'd like to include before I wrap this up. Some people say Christianity is a crutch. That it's only for the weak. That is true. But what so many people don't realize is that we're ALL weak. And if you refuse a crutch because you don't want to seem weak, but in reality you're missing a leg (and somehow you haven't noticed), you really won't be any better off. You still won't be able to walk, no matter how hard you try. The guy who accepts the crutch, however, realizes and accepts his weakness, and ends up getting around a lot better than the other guy.
So I guess my point is, accept your weakness. God's strength is made perfect in weakness, anyway. And he knows you can't be holy on your own. So (this is especially what I need to hear) stop being disappointed in yourself, stop trying to be holy on your own, and just draw near to God and let the Spirit guide you.
Simple, but incredibly, incredibly hard to do.
