1 Cor 13

Last night I read 1 Cor 13 - the famous chapter that gets quoted at weddings so often on one can stand to hear it anymore. But it actually is a really good chapter, so please indulge me as I explore it.
As I read about love, I realized that I don't trust feelings. I trust a my knowledge that God loves me, but when I feel that love, I have in the back of my mind that the feeling won't last. But there's one problem with poo-pooing the side of love that's a feeling - I wouldn't be with God if I didn't feel He loved me. Yes, there are times when I don't feel the love, but if I never did, there'd be no incentive to be a Christian.
But if love is a feeling, how can I trust it? Right now I can feel it, but what happens when it fades? Nothing in my life is anything without it. I've written before that I can go on because God is, but I really mean that I can go on because God is love. If He were grace, whoopie. So my sins are forgiven. What does that get me except the promise that I'll fly around some after I die? If He were truth? so what? I would have the right answer, but no reason to care. I'm looking for a feeling.
That feeling can be combined with knowledge that God loves me, but if I go for long enough with just knowledge, I'll die of misery. The knowledge that God is love whether I feel it or not isn't the kind of knowledge I think is helpful. The kind of knowledge that helps is the knowledge that when I don't feel it, I know where to go looking for it.
I can't live for the knowledge of love, and if I don't have it I certainly can't spread it. But I don't have to be scared of this feeling. God's love is the one feeling that can be trusted, because He is love. God is always there, and so is His love.
