Sometimes I think we're all in danger of getting desensitized to 1 Cor 13, in a similar way to John 3:16. It's a passage that's read at nearly every wedding I attend! But I actually don't think we can ever examine it too often. Like Rachel, I know when I read that definition of "love" that I have miles left to go before I am living it out.
1 Cor 13:8-13
Love never ends. As for prophecies, they will pass away; as for tongues, they will cease; as for knowledge, it will pass away. For we know in part and we prophesy in part, but when the perfect comes, the partial will pass away. When I was a child, I spoke like a child, I thought like a child, I reasoned like a child. When I became a man, I gave up childish ways. For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known.
So now faith, hope, and love abide, these three; but the greatest of these is love.
