The Function of the Law
Galatians 3:19
Why then serves the law? It was added because of transgressions, till the seed should come to whom the promise was made…


Of what use, then, is the law, if (as you assert) it is not simply a codicil to — a substitute for — God's promise to Abraham? "It was added." Not being a part of the original scheme, but made necessary on account of the hardness of men's hearts, it came in as a sort of marginal addition or parenthesis in the dealings of God with the Jews. The moral atmosphere was changed. In circumstances of amity the promise had been given, God speaking to Abraham as a man with his friend; in circumstances of discord, with suitable accompaniment of hailstones and coals of fire, the law was promulgated and enforced. The function of the law was to assist as an ally: to be subsidiary to the promise, and help towards its fulfilment. This it did by revealing men's deeds to them in their true light — showing them their own sinfulness in the sight of God, and their own inability to do anything towards mending matters — a necessary preliminary to their attainment of that faith which would lead them to embrace the promise. The law, again, was merely a temporary, enactment; its work would be done when He Should appear to whom the promise had been made. Still further: the provisional nature of the law may be perceived, if we consider the manner of its promulgation. "It was ordained through angels in the hand of a mediator." Direct had been God's communication with Abraham when He gave the promise; but at the giving of the law He delivered His decrees to angels, and the angels entrusted them to a second intermediate agent, viz., Moses. Now the existence of a mediator (or go-between) implies duality, separation, disunion; whereas a promise is a simple direct transaction requiring no such intervention. If there had not been discord, at the time of the giving of the law, a mediator would have been out of place; he would have had no business there at all. There was discord at that time; and for that reason Moses was appointed to mediate. But this, instead of proving that the law is antagonistic to the promise, proves exactly the contrary, for — "God is one." If the law had been intended to annul the promise, it would necessarily follow that God had changed His mind, His dealings with the children of Israel through Moses would contradict His dealings four hundred and thirty years before with Abraham. Such a thought cannot for a moment be tolerated. The Lord our God is one Lord; with Him is no variableness, neither shadow of turning. He is ever one and the same; and the eternal principles upon which He acts can never alter. However different and opposed to one another His various dispensations towards mankind may at first sight appear, a secret thread of harmony runs through them all. His unity of purpose is expressed from first to last, in unity of plan. He will justify the circumcision by faith, and the uncircumcision by the same faith — in Jesus Christ, the seed of Abraham, to whom the promise was made. Now it is easy to see in what sort of relation the law stands to the promise. The work of the law is a work of discipline. It presents to view the sterner side of the Divine character; it shows God frowning at sin, and holding aloof from the sinner; it teaches man that by no effort of his own can he regain that communion with his Maker which was forfeited at the fall. But if that communion is not regained, man is lost — hopelessly lost for ever. Is there no other means of recovering the forfeited possession, and of once more enjoying the privilege of basking in the light of the Divine countenance? Yes, there is; and surely the law has been a most useful and valuable institution, if it has led men to ask that question. The promise, given hundreds of years before the law, still remains in force. Nothing can abrogate it — seeing that God is one and the same both in essence and in will. If in the time of Abraham He was willing to justify by faith, He is willing to justify by faith now, and He will continue in the same mind to the end of time and throughout eternity. Thus is the law our pedagogue, taking us by the hand, and leading us back over rough and devious paths to that earlier promise which was made to Christ the true seed of Abraham, and, in Christ, to all who believe.
