A man walking through a wall is a miracle. A man both walking and not walking through a wall at the same time and in the same respect is a contradiction. God can perform miracles but not contradictions - not because his power is limited, but because contradictions are meaningless.

Thus moral theology leads us four steps deeper than law. To fulfill the moral law, we need love. To get love, we need union with God. To get union with God, we need the new birth. And to get the new birth, we need faith.

God'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.

For the wise men of old, the cardinal problem of human life was how to conform the soul to objective reality, and the solution was wisdom, self-discipline, and virtue. For the modern, the cardinal problem is how to conform reality to the wishes of man, and the solution is a technique.

No sane person wants hell to exist. No sane person wants evil to exist. But hell is just evil eternalized. If there is evil and if there is eternity, there can be hell. If it is intellectually dishonest to disbelieve in evil just because it is shocking and uncomfortable, it is the same with hell. Reality has hard corners, surprises, and terrible dangers in it. We desperately need a true road map, not nice feelings, if we are to get home. It is true, as people often say, that "hell just feels unreal, impossible." Yes. So does Auschwitz. So does Calvary.

Christ is the Word of God in person. The Bible is the Word of God in writing. Both are the Word of God in the words of men. Both have a human nature and a divine nature.

God created the possibility of evil; people actualized that potentiality. The source of evil is not God's power but mankind's freedom. Even an all-powerful God could not have created a world in which people had genuine freedom and yet there was no potentiality for sin, because our freedom includes the possibility of sin within its own meaning.
