“When God made promise to Abraham, because He could swear by no greater, He sware by Himself; ... for men verily swear by the greater; and an oath for confirmation is to them an end of all strife. Wherein God, willing more abundantly to show unto the heirs of promise the immutability of His counsel, confirmed it by an oath; that by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us; which hope we have as an anchor of the soul, both sure and steadfast, and which entereth into that within the veil; whither the forerunner is for us entered, even Jesus, made an high priest forever after the order of Melchizedek.” Heb. 6:13-20. Compare Gen. 22:15-18. It was the oath of God, therefore, that confirmed the covenant made to Abraham; that promise and oath to Abraham are our ground of hope, our strong consolation; they are “sure and steadfast,” because the oath sets forth Christ as the pledge, the surety, and “He ever liveth.” He upholds all things by the word of His power. Heb. 1:3. “In Him all things consist.” Col. 1:17, R. V. Therefore, when God “interposed Himself by an oath,” which is our consolation and hope in fleeing for refuge from sin, He pledged His own existence, and with it the entire universe, for our salvation. Surely a firm foundation for our hope is laid in His excellent Word. [Sidenote: The Law Can Not Make the Covenant Void.] Do not forget as we proceed that the covenant and the promise are the same thing, and that it conveys land, even the whole earth made new, to Abraham and his seed; and remember also that, since only righteousness is to dwell in the new heavens and the new earth promised to Abraham and his seed, the promise includes the making righteous of all who believe. This is done in Christ, in whom the promise is confirmed. Now, “though it be but a man’s covenant, yet if it be confirmed, no man disannulleth, or addeth thereto.” Gal. 3:15. How much more must this be the case with God’s covenant! Therefore, since perfect and everlasting righteousness was assured by the covenant made with Abraham, which was also confirmed in Christ, by the oath of God, it is impossible that the law, which was spoken four hundred and thirty years later, could introduce any new feature. The inheritance was given to Abraham by promise, but if after four hundred and thirty years it should transpire that now the inheritance must be gained in some other way, then the promise would be of no effect, and the covenant would be made void. But that would involve the overthrow of God’s government, and the ending of His existence; for He pledged His own existence to _give_ Abraham and his seed the inheritance and the righteousness necessary for it. “For the promise, that he should be the heir of the world, was not to Abraham, or to his seed, through the law, but through the righteousness of faith.” Rom. 4:13.
