Romans 7:3-4

Ye also are become dead to the law; i.e. ye are taken off from all hopes of justification by it, and from your confidence in obedience to it, Galatians 2:19. The opposition seems to require that he should have said, the law is dead to us; but these two phrases are much the same.

Question. What law does he mean?

Answer. Not only the ceremonial, but the moral law, for in that he instances, Romans 7:7. The moral law is in force still; Christ came to confirm, and not to destroy it; but believers are freed from the malediction, from the rigid exaction, and from the irritation thereof. Of this last he speaks, Romans 7:8,Romans 7:9, and from it we are freed but in part.

By the body of Christ; i.e. by the sacrifice of Christ’s body upon the cross; thereby he delivered us from the law, in the sense before mentioned.

Fruit unto God; i.e. fruits of holiness and good works, to the glory and praise of God.
