Galatians 3:15-18 - The Promise To Abraham And His Descendant
15 Brethren, (I speak after the manner of men,) no one cancelleth or addeth to a covenant which hath been ratified, though it be but the covenant of a man. 16 Now the promises were made to Abraham, and to his seed. He doth not say, "and to seeds," as of many; but as of one, "and to thy seed," which is Christ. 17 This then I say, that the law, which was given four hundred and thirty years after, cannot disannul the covenant, which was so long before confirmed by God unto Christ, to make void the promise. 18 For if the inheritance be from the law, it is no more from the promise: whereas God gave it to Abraham by promise.
