“Do we then make void the law through faith? God forbid: yea, we establish the law.”
King James Version (KJV)
3:31 We establish the law - Both the authority, purity, and the end of it; by defending that which the law attests; by pointing out Christ, the end of it; and by showing how it may be fulfilled in its purity.
Ro 3:31 Do we then make void the law? Do we make it useless through "the faith"; i.e., through the Gospel? (the article is found before "faith" in the Greek). We establish the law. Rather, "law" (the article is not found in the Greek). Law is confirmed and rendered sacred, when its just demands are met by the suffering of the Son of God himself.
