Galatians 3:15-18 - The Promise To Abraham And His Descendant
15 Brethren, I speak according to the practice of men; contracts between men, when once ratified, cannot be disannulled or altered afterwards by any man. 16 now to Abraham and his offspring were the promises made. he does not say, "to offsprings," as if he spoke of many; but as speaking of one, "and to thy offspring," which means Christ. 17 this therefore I say, that the law, which was not till four hundred and thirty years after, cannot disannul the promise, that was ratified before by God, so as to set the promise afoot. 18 now if the right to the inheritance be from the law, it is no longer founded upon the promise; altho' God made a donation of it to Abraham by promise.
