The more we realize we are loved, the more ashamed we are not to love back. The more we sin as a violation of love, not just of law, the more powerful a motive we will have to overcome it. For sin is attractive to us (otherwise we would never be attracted to it) and can be cast out only by something more attractive.
Peter KreeftGod's love is as objective as light. Because the sun in a sense is light, or the source of light rather than being lit, it really gives its light to the earth. And because the earth really receives light from the sun, it is really transformed every morning from darkness to light. Just as objectively, because God is love, God really gives love to us. And because we receive real life-changing love from God, we are really transformed from darkness to light.
Peter KreeftWe are all insane. That is what original sin means. Sin is insanity. It is preferring finite joy to infinite joy, creatures to the Creator, an unhappy, Godless self to a happy, God-filled self Only God can save us from this disease. That is what the name "Jesus" means: 'God saves'.
