So again in Deuteronomy 24 the question of divorce is treated, where we must say that a certain allowance was made them for the wilfulness of man in this respect. This is no matter of opinion; for our Lord Jesus Christ has ruled in this. Nobody can understand the law aright, or the Scriptures of the Old Testament in general, unless he bear in mind that in it God is dealing with man as such. Consequently, though there is wisdom and goodness and righteousness, it is man in the flesh under trial, and hence it is not yet the perfection of the divine mind displayed. This last is only found when Christ comes. The first Adam is not the Second; and it was with the first man that God was then at work. No part of the law lacks the wisdom of God; but, Christ not being yet revealed, He did not as a fact go beyond man as he then was. To have brought in what was suitable for the Second man could not have applied to Israel in their then condition.
And God, it seems to me, has distinctly marked this in Scripture even in an outward fashion, inasmuch as He has not been pleased to give us His word even in the same tongue. The standing witness against the folly of confounding the two Testaments finds its rebuke in the patent fact that the Old Testament is in one language, the New Testament in another. So plain a difference on its very face one might have thought it impossible to overlook; but even believers accept shortsightedness in divine things, and just so far as tradition influences them; for people scarcely think about Scripture, and thus they do not know how to apply the clearest and surest facts, as well as God’s words, before all eyes.
But there is much more than the use of different languages – there is the difference between the first man fallen into sin and the Second man who first descended into the lower parts of the earth, and then ascended above the heavens after accomplishing the mighty work of redemption. Assuredly this is all the difference possible, and it is just what reigns between the Old and the New Testament, not in the hearts of saints, but as a state of things. Consequently, the relationship is altogether of another sort. Hence the provisions that were suitable and appropriate, when God had as an object before Him the first man, could not apply to the Second, under whose revelation and redemption we find ourselves. This must be borne in mind if we would judge rightly about these types, or the law in general which made nothing perfect.
