Galatians 3:15-18 - The Promise To Abraham And His Descendant

15 Brethren, I speak according to what is practised among men; no one sets aside even a human covenant, or makes additions to it, after it has been ratified. 16 But the promises were made to Abraham and "to his offspring." He doth not say, "and to offsprings," as speaking of many, but, as speaking of one, "and to thy offspring," which is Christ. 17 And what I mean is this; that a covenant that was before ratified by God, the Law, which came four hundred and thirty years after, cannot annul, so as to make void the promise; 18 for if the inheritance cometh from the Law, it ceaseth to be the consequence of the promise; but to Abraham God gave it by promise.
