Galatians 3:15-22

¹⁵ Brethren, (I speak according to man,) even man's confirmed covenant no one sets aside, or adds other dispositions to. ¹⁶ But to Abraham were the promises addressed, and to his seed: he does not say, And to seeds, as of many; but as of one, And to thy seed; which is Christ. ¹⁷ Now I say this, A covenant confirmed beforehand by God, the law, which took place four hundred and thirty years after, does not annul, so as to make the promise of no effect. ¹⁸ For if the inheritance [be] on the principle of law, [it is] no longer on the principle of promise; but God gave it in grace to Abraham by promise.

The Purpose of the Law

¹⁹ Why then the law? It was added for the sake of transgressions, until the seed came to whom the promise was made, ordained through angels in [the] hand of a mediator. ²⁰ But a mediator is not of one, but God is one. ²¹ [Is] then the law against the promises of God? Far be the thought. For if a law had been given able to quicken, then indeed righteousness were on the principle of law; ²² but the scripture has shut up all things under sin, that the promise, on the principle of faith of Jesus Christ, should be given to those that believe.
