In Romans 7, St. Paul says, "The law is spiritual." What does that mean? If the law were physical, then it could be satisfied by works, but since it is spiritual, no one can satisfy it unless everything he does springs from the depths of the heart. But no one can give such a heart except the Spirit of God, who makes the person be like the law, so that he actually conceives a heartfelt longing for the law and henceforward does everything, not through fear or coercion, but from a free heart.

A Christian is never in a state of completion but always in a process of becoming.

Our works do not generate righteousness, rather our righteousness in Christ generates works.

If the heart has been reformed by the spirit, it makes use of both the useful and delightful things created and given by God in a holy manner and with thanksgiving.

The law of God cannot be fulfilled by external obedience.

The proverb has it that Hunger is the best cook. The Law makes afflicted consciences hungry for Christ. Christ tastes good to them. Hungry hearts appreciate Christ. Thirsty souls are what Christ wants. He invites them: Come unto me, all ye that labour and are heavy laden, and I will give you rest. Christ's benefits are so precious that He will dispense them only to those who need them and really desire them.

Good works are the seals and proofs of faith; for even as a letter must have a seal to strengthen the same, even so faith must have good works.
