“Is the Lawe then against the promises of God? God forbid: for if there had beene a Lawe giuen which could haue giuen life, verily righteousnesse should haue bene by the Law.”
1611 King James Version (KJV)
3:21 Will it follow from hence that the law is against, opposite to, the promises of God? By no means. They are well consistent. But yet the law cannot give life, as the promise doth. If there had been a law which could have given life - Which could have entitled a sinner to life, God would have spared his own Son, and righteousness, or justification. with all the blessings consequent upon it, would have been by that law.
Ga 3:21 [Is] the law then against the promises of God? No. The law does not give life at all. If it did, and could impart righteousness, then it might be said to be opposed to the promises of righteousness by faith.
