Some saints have taught that as we come to know God better we come to know ourselves better. The converse is also true: more thorough self-knowledge enables us to appreciate God more. He reveals us to ourselves according to what we can stand to look at. In the end he reveals the beauty that he put in us in the first place. The truth about any of us is that we are flawed reflections of the divine. Neither pessimism nor naive optimism have any place in the Christian view of human nature. In the next world, we will become more nearly like God and see God and ourselves as we really are. There will be no pain in that vision.
Though it is hard at the beginning of the spiritual life to believe that God loves us as we are, that is, in fact, the marvelous truth that Jesus proclaimed again and again in his words and actions during his earthly career. He never tired and never tires of reaching out to the flawed children of his Father to bring us into full union with God.
By your grace, I come before you, Lord Jesus, as I am, fully confident that you will accept me. I want to become more like you. I believe you want this too.
