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.
