For the present we may pass by the question of time involved in the phrase, “till the Seed should come, to whom the promise was made,” since our present study is the relation of the law to the promise. The law was given to the people from Sinai “in the hand of a Mediator.” Who was this Mediator?—There can be only one answer: “There is one God, and one Mediator between God and men, the Man Christ Jesus.” 1 Tim. 2:5. “Now a mediator is not a mediator of one, but God is one.” God is one, the people are the other, and Christ Jesus is the Mediator. Just as surely as God is one party to the transaction, Christ must be the Mediator, for there is no other mediator between God and men. “Neither is there salvation in any other; for there is none other name under heaven given among men, whereby we must be saved.” Acts 4:12.
Christ’s Work as Mediator.
Man has wandered from God, and rebelled against Him. “All we like sheep have gone astray.” Our iniquities have separated between us and Him. Isa. 59:1, 2. “The carnal mind is enmity against God; for it is not subject to the law of God, neither indeed can be.” Rom. 8:7. Christ came that He might destroy the enmity, and reconcile us to God; for He is our peace. Eph. 2:14-16. Christ “suffered for sins, the Just for the unjust, that He might bring us to God.” 1 Peter 3:18. Through Him we have access to God. Rom. 5:1, 2; Eph. 2:18. In Him the carnal mind, the rebellious mind, is taken away, and the mind of the Spirit given in its stead, “that the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.” Rom. 8:3, 4. Christ’s work is to save that which was lost, to restore that which was broken, to reunite that which was separated. His name is “God with us;” and so with Him dwelling in us we are made “partakers of the Divine nature.” 2 Peter 1:4.
It should be understood that Christ’s work as Mediator is not limited either as to time or extent. To be Mediator means more than to be intercessor. Christ was Mediator before sin came into the world, and will be Mediator when no sin is in the universe, and no need for expiation. “In Him all things consist.” He is the very impress of the Father’s being. He is the life. Only in and through Him does the life of God flow to all creation. He is, then, the means, medium, mediator, the way, by which the light of life pervades the universe. He did not first become Mediator at the fall of man, but was such from eternity. No one, not simply no man, but no created being, comes to the Father but by Christ. No angel can stand in the Divine presence except in Christ. No new power was developed, no new machinery, so to speak, was required to be set in motion by the entering of sin into the world. The power that had created all things only continued in God’s infinite mercy, to work for the restoration of that which was lost. In Christ were all things created, and, therefore, in Him we have redemption through His blood. Col. 1:14-17. The power that pervades and upholds the universe is the power that saves us. “Now unto Him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us, unto Him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.”
The Law Not against the Promise.
“Is the law then against the promises of God?”—Not by any means. Far from it. If it were, it would not be in the hands of a Mediator, Christ; for all the promises of God are in Him. 2 Cor. 1:20. So we find the law and the promise combined in Christ. We may know that the law was not and is not against the promises of God, from the fact that God gave both the promise and the law. We know, also, that the giving of the law introduced no new element into the covenant, since, having been confirmed, nothing could be added to or taken from it. But the law is not useless, else God would not have given it. It is not a matter of indifference whether we keep it or not, for God commands it. But, all the same, it is not against the promise, and brings no new element in. Why?—Simply because the law is in the promise. The promise of the Spirit includes this: “I will put My laws into their mind, and write them in their hearts.” Heb. 8:10. And this is what God indicated had been done for Abraham when “He gave him the covenant of circumcision.” Read Rom. 4:11; 2:25-29; Phil. 3:3.
The Law Magnifies the Promise.
The law, as already seen, is not against the promise, because it is in the promise. The promise that Abraham and his seed should inherit the world, was “through the righteousness of faith.” But the law is righteousness, as God says: “Harken unto Me, ye that know righteousness, the people in whose heart is My law.” Isa. 51:7. So, then, the righteousness which the law demands is the only righteousness that can inherit the promised land, but it is obtained, not by the works of the law, but by faith. The righteousness of the law is not attained by human efforts to do the law, but by faith. See Rom. 9:30-32. Therefore, the greater the righteousness which the law demands, the greater is seen to be the promise of God; for He has promised to give it to all who believe. Yea, He has sworn it. When, therefore, the law was spoken from Sinai, “out of the midst of the fire, of the cloud, and of the thick darkness, with a great voice,” accompanied by the sounding of the trump of God, and with the whole earth quaking at the presence of the Lord and all His holy angels, thus indicating the inconceivable greatness and majesty of the law of God, it was, to every one who remembered the oath of God, but a revelation of the wondrous greatness of God’s promise; for all the righteousness which the law demands, He has sworn to give to every one who trusts Him. The “loud voice” with which the law was spoken, was the loud voice that from the mountain-tops proclaims the glad tidings of the saving mercy of God. See Isa. 40:9. God’s precepts are promises; they must necessarily be such, because He knows that men have no power. All that God requires is what He gives. When He says, “Thou shalt not,” we may take it as His assurance that if we but trust Him He will preserve us from the sin against which He warns us. He will keep us from falling.
Conviction of Sin and of Righteousness.
Jesus said of the Comforter, “When He is come, He will reprove the world of sin, and of righteousness, and of judgment.” John 16:8. Of Himself He said, “I came not to call the righteous, but sinners to repentance.” Mark 2:17. “They that are whole have no need of the physician, but they that are sick.” A man must feel his need before he will accept help; he must know his disease before he can apply the remedy. Even so the promise of righteousness will be utterly unheeded by one who does not realize that he is a sinner. The first part of the comforting work of the Holy Spirit, therefore, is to convince men of sin. So “the Scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.” “By the law is the knowledge of sin.” Rom. 3:20. He who knows that he is a sinner is in the way to acknowledge it; and “if we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.” 1 John 1:9. Thus the law is in the hands of the Spirit an active agent in inducing men to accept the fulness of the promise. No one hates the man who has saved his life by pointing out to him an unknown peril; on the contrary, such an one is regarded as a friend, and is always remembered with gratitude. Even so will the law be regarded by the one who has been prompted by its warning voice to flee from the wrath to come. He will ever say, with the psalmist, “I hate vain thoughts, but Thy law do I love.”
