Now, it is to St. Paul that we turn for light upon the connection between the Old Testament and the New. And he distinctly lays down two great principles. The first is that the Old Testament is meant to educate men for the New; and especially that the sense of failure, impressed upon men's consciences by the stern demands of the Law, was necessary to make them accept the Gospel.
The law was our schoolmaster to bring us to Christ: it entered that sin might abound. And it is worth notice that this effect was actually wrought, not only upon the gross transgressor by the menace of its broken precepts, but even more perhaps upon the high-minded and pure, by the creation in their breasts of an ideal, inaccessible in its loftiness. He who says, All these things have I kept from my youth up, is the same who feels the torturing misgiving, What good thing must I do to attain life?... What lack I yet? He who was blameless as touching the righteousness of the law, feels that such superficial innocence is worthless, that the law is spiritual and he is carnal, sold under sin.
Now, this principle need by no means be restricted to the Mosaic institutions. If this were the object of the law, it would probably explain much more. And when we return to the Old Testament with this clue, we find every condition in life examined, every social and political experiment exhausted, a series of demonstrations made with scientific precision, to refute the arch-heresy which underlies all others--that in favourable circumstances man might save himself, that for the evil of our lives our evil surroundings are more to be blamed than we.
Innocence in prosperous circumstances, unwarped by evil habit, untainted by corruption in the blood, uncompelled by harsh surroundings, simple innocence had its day in Paradise, a brief day with a shameful close. God made man upright, but he sought out many inventions, until the flood swept away the descendants of him who was made after the image of God.
Next we have a chosen family, called out from all the perilous associations of its home beyond the river, to begin a new career in a new land, in special covenant with the Most High, and with every endowment for the present and every hope for the future which could help to retain its loyalty. Yet the third generation reveals the thirst of Esau for his brother's blood, the treachery of Jacob, and the distraction and guilt of his fierce and sensual family. It is when individual and family life have thus proved ineffectual amid the happiest circumstances, that the tribe and the nation essay the task. Led up from the furnace of affliction, hardened and tempered in the stern free life of the desert, impressed by every variety of fortune, by slavery and escape, by the pursuit of an irresistible foe and by a rescue visibly divine, awed finally by the sublime revelations of Sinai, the nation is ready for the covenant (which is also a challenge)--The man that doeth these things shall live by them: if thou diligently hearken unto the voice of the Lord thy God ... He shall set thee on high above all nations.
Such is the connection between this narrative and what went before. And the continuation of the same experiment, and the same failure, can be traced through all the subsequent history. Whether in so loose an organisation that every man does what is right in his own eyes, or under the sceptre of a hero or a sage,--whether so hard pressed that self-preservation ought to have driven them to their God, or so marvellously delivered that gratitude should have brought them to their knees,--whether engulfed a second time in a more hopeless captivity, or restored and ruled by a hierarchy whose authority is entirely spiritual,--in every variety of circumstances the same melancholy process repeats itself; and lawlessness, luxury, idolatry and self-righteousness combine to stop every mouth, to make every man guilty before God, to prove that a greater salvation is still needed, and thus to pave the way for the Messiah.
