15Brothers, as men would say, even a man's agreement, when it has been made certain, may not be put on one side, or have additions made to it.
16Now to Abraham were the undertakings given, and to his seed. He says not, And to seeds, as of a great number; but as of one, he says, And to your seed, which is Christ.
17Now this I say: The law, which came four hundred and thirty years after, does not put an end to the agreement made before by God, so as to make the undertaking without effect.
18Because if the heritage is by the law, it is no longer dependent on the word of God; but God gave it to Abraham by his word.
19What then is the law? It was an addition made because of sin, till the coming of the seed to whom the undertaking had been given; and it was ordered through angels by the hand of a go-between.
20Now a go-between is not a go-between of one; but God is one.
21Is the law then against the words of God? in no way; because if there had been a law which was able to give life, truly righteousness would have been by the law.
