The Expositor's Bible: The Epistle to the Galatians

by George G. Findlay

1. For the sake of transgressions. In other words, the object of the law of Moses was to develope sin. This is not the whole of the Apostle's answer; but it is the key to his explanation. This design of the Mosaic revelation determined its form and character. Here is the standpoint from which we are to estimate its working, and its relation to the kingdom of grace. The saying of Rom. v. 20 is Paul's commentary upon this sentence: "The law came in by the way, in order that the trespass (of Adam) might multiply." The same necessity is expressed in the paradox of 1 Cor. xv. 56: "The strength of sin is the law."

This enigma, as a psychological question, is resolved by the Apostle in Rom. vii. 13-24. The law acts as a spur and provocative, rousing the power of sin to conscious activity. However good in itself, coming into contact with man's evil flesh, its promulgation is followed inevitably by transgression. Its commands are so many occasions for sin to come into action, to exhibit and confirm its power. So that the Law practically assumes the same relation to sin as that in which the Promise stands to righteousness and life. In its union with the Law our sinful nature perpetually "brings forth fruit unto death." And this mournful result God certainly contemplated when He gave the Law of Moses.

But are we compelled to put so harsh a sense on the Apostle's words? May we not say that the Law was imposed in order to restrain sin, to keep it within bounds? Some excellent interpreters read the verse in this way. It is quite true that, in respect of public morals and the outward manifestations of evil, the Jewish law acted beneficially, as a bridle upon the sinful passions. But this is beside the mark. The Apostle is thinking only of inward righteousness, that which avails before God. The wording of the clause altogether excludes the milder interpretation. For the sake of (χάριν, Latin gratia) signifies promotion, not prevention. And the word transgression, by its Pauline and Jewish usage, compels us to this view.[100] Transgression presupposes law. It is the specific form which sin takes under law—the re-action of sin against law. What was before a latent tendency, a bias of disposition, now starts to light as a flagrant, guilty fact. By bringing about repeated transgressions the Law reveals the true nature of sin, so that it "becomes exceeding sinful." It does not make matters worse; but it shows how bad they really are. It aggravates the disease, in order to bring it to a crisis. And this is a necessary step towards the cure.

2. The Law of Moses was therefore a provisional dispensation,—"added until the seed should come to whom the promise hath been made." Its object was to make itself superfluous. It "is not made for a righteous man; but for the lawless and unruly" (1 Tim. i. 9). Like the discipline and drill of a strictly governed boyhood, it was calculated to produce a certain effect on the moral nature, after the attainment of which it was no longer needed and its continuance would be injurious. The essential part of this effect lay, however, not so much in the outward regularity it imposed, as in the inner repugnancy excited by it, the consciousness of sin unsubdued and defiant. By its operation on the conscience the Law taught man his need of redemption. It thus prepared the platform for the work of Grace. The Promise had been given. The coming of the Covenant-heir was assured. But its fulfilment was far off. "The Lord is not slack concerning His promise,"—and yet it was two thousand years before "Abraham's seed" came to birth. The degeneracy of the patriarch's children in the third and fourth generation showed how little the earlier heirs of the Promise were capable of receiving it. A thousand years later, when the Covenant was renewed with David, the ancient predictions seemed at last nearing their fulfilment. But no; the times were still unripe; the human conscience but half-disciplined. The bright dawn of the Davidic monarchy was overclouded. The legal yoke is made more burdensome; sore chastisements fall on the chosen people, marked out for suffering as well as honour. Prophecy has many lessons yet to inculcate. The world's education for Christ has another millennium to run.

Nor when He came, did "the Son of man find faith in the earth"! The people of the Law had no sooner seen than they hated "Him to whom the law and the prophets gave witness." Yet, strangely enough, the very manner of their rejection showed how complete was the preparation for His coming. Two features, rarely united, marked the ethical condition of the Jewish people at this time—an intense moral consciousness, and a deep moral perversion; reverence for the Divine law, combined with an alienation from its spirit. The chapter of Paul's autobiography to which we have so often referred (Rom. vii. 7-24) is typical of the better mind of Judaism. It is the ne plus ultra of self-condemnation. The consciousness of sin in mankind has ripened.

3. And further, the Law of Moses revealed God's will in a veiled and accommodated fashion, while the Promise and the Gospel are its direct emanations. This is the inference which we draw from vv. 19, 20.

We are well aware of the extreme difficulty of this passage. Ver. 20 has received, it is computed, some four hundred and thirty distinct interpretations. Of all the "hard things our beloved brother Paul" has written, this is the very hardest. The words which make up the sentence are simple and familiar; and yet in their combination most enigmatic. And it stands in the midst of a paragraph among the most interesting and important that the Apostle ever wrote.

Let us look first at the latter clause of ver. 19: "ordained through angels, in the hand (i.e. by means) of a mediator." These circumstances, as the orthodox Jew supposed, enhanced the glory of the Law. The pomp and formality under which Mosaism was ushered in, the presence of the angelic host to whose agency the terrific manifestations attending the Law-giving were referred, impressed the popular mind with a sense of the incomparable sacredness of the Sinaitic revelation. It was this assumption which gave its force to the climax of Stephen's speech, of which we hear an echo in these words of Paul: "who received the law at the disposition of angels—and have not kept it!"[101] The simplicity and informality of the Divine communion with Abraham, and again of Christ's appearance in the world and His intercourse with men, afford a striking contrast to all this.

More is hinted than is expressly said in Scripture of the part taken by the angels in the Law-giving. Deut. xxxiii. 2[102] and Ps. lxviii. 17 give the most definite indications of the ancient faith of Israel on this point. But "the Angel of the Lord" is a familiar figure of Old Testament revelation. In Hebrew thought impressive physical phenomena were commonly associated with the presence of spiritual agents.[103] The language of Heb. i. 7 and ii. 2 endorses this belief, which in no way conflicts with natural science, and is in keeping with the Christian faith.

But while such intermediacy, from the Jewish standpoint, increased the splendour and authority of the Law, believers in Christ had learned to look at the matter otherwise.[104] A revelation "administered through angels," spoke to them of a God distant and obscured, of a people unfit for access to His presence. This is plainly intimated in the added clause, "by means of a mediator,"—a title commonly given to Moses, and recalling the entreaty of Exod. xx. 19; Deut. v. 22-28: "The people said, Speak thou with us, and we will hear; but let not God speak with us, lest we die." These are the words of sinful men, receiving a law given, as the Apostle has just declared, on purpose to convict them of their sins. The form of the Mosaic revelation tended therefore in reality not to exalt the Law, but to exhibit its difference from the Promise and the distance at which it placed men from God.
