39. But now to come to something more definite. We have an example of the calm, subdued style in the Apostle Paul, where he says: "Tell me, ye that desire to be under the law, do ye not hear the law? For it is written, that Abraham had two sons; the one by a bond maid, the other by a free woman. But he who was of the bond woman was born after the flesh; but he of the free woman was by promise. Which things are an allegory: for these are the two covenants; the one from the Mount Sinai, which gendereth to bondage, which is Hagar. For this Hagar is Mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children. But Jerusalem which is above is free, which is the mother of us all;" and so on. And in the same way where he reasons thus: "Brethren, I speak after the manner of men: Though it be but a man's covenant, yet if it be confirmed, no man disannulleth, or addeth thereto. Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ. And this I say, that the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect. For if the inheritance be of the law, it is no more of promise: but God gave it to Abraham by promise." And because it might possibly occur to the hearer to ask, If there is no inheritance by the law, why then was the law given? he himself anticipates this objection and asks, "Wherefore then serveth the law?" And the answer is given: "It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator. Now a mediator is not a mediator of one; but God is one." And here an objection occurs which he himself has stated: "Is the law then against the promises of God?" He answers: "God forbid." And he also states the reason in these words: "For if there had been a law given which could have given life, verily righteousness should have been by the law. But the Scripture has concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe." It is part, then, of the duty of the teacher not only to interpret what is obscure, and to unravel the difficulties of questions, but also, while doing this, to meet other questions which may chance to suggest themselves, lest these should cast doubt or discredit on what we say. If, however, the solution of these questions suggest itself as soon as the questions themselves arise, it is useless to disturb what we cannot remove. And besides, when out of one question other questions arise, and out of these again still others; if these be all discussed and solved, the reasoning is extended to such a length, that unless the memory be exceedingly powerful and active, the reasoner finds it impossible to return to the original question from which he set out. It is, however, exceedingly desirable that whatever occurs to the mind as an objection that might be urged should be stated and refuted, lest it turn up at a time when no one will be present to answer it, or lest, if it should occur to a man who is present but says nothing about it, it might never be thoroughly removed.
