If God is holy and pure, and we are sinful and soiled, how can we possibly become one with him? Well, God is light and we are in darkness if we reject him. Do not see union as the blending of the pure and the impure; rather, see it as light wiping out darkness. Our sins cannot stain God, but in the presence of his light, darkness can no longer exist. Therefore, let the light of Jesus take away all your sins, including the sin of not surrendering to him, and you are in union with him.
