On Marriage and Concupiscence

That, therefore, which is born of the lust of the flesh is really born of the world, and not of God; but it is born of God, when it is born again of water and of the Spirit. The guilt of this concupiscence, regeneration alone remits, even as natural generation contracts it. What, then, is generated must be regenerated, in order that likewise since it cannot be otherwise, what has been contracted may be remitted. It is, no doubt, very wonderful that what has been remitted in the parent should still be contracted in the offspring; but nevertheless such is the case.

That this mysterious verity, which unbelievers neither see nor believe, might get some palpable evidence in its support, God in His providence has secured in the example of certain trees. For why should we not suppose that for this very purpose the wild olive springs from the olive? Is it not indeed credible that, in a thing which has been created for the use of mankind, the Creator provided and appointed what should afford an instructive example, applicable to the human race?

It is a wonderful thing, then, how those who have been themselves delivered by grace from the bondage of sin, should still beget those who are tied and bound by the self-same chain, and who require the same process of loosening? Yes; and we admit the wonderful fact. But that the embryo of wild olive trees should latently exist in the germs of true olives, who would deem credible, if it were not proved true by experiment and observation? In the same manner, therefore, as a wild olive grows out of the seed of the wild olive, and from the seed of the true olive springs also nothing but a wild olive, notwithstanding the very great difference there is between the wild olive and the olive; so what is born in the flesh, either of a sinner or of a just man, is in both instances a sinner, notwithstanding the vast distinction which exists between the sinner and the righteous man.

He that is begotten is no sinner as yet in act, and is still new from his birth; but in guilt he is old. Human from the Creator, he is a captive of the destroyer, and needs a redeemer. The difficulty, however, is how a state of captivity can possibly befall the offspring, when the parents have been themselves previously redeemed from it. Now it is no easy matter to unravel this intricate point, or to explain it in a set discourse; therefore unbelievers refuse to accept it as true; just as if in that other point about the wild olive and the olive, which we gave in illustration, any reason could be easily found, or explanation clearly given, why the self-same shoot should sprout out of so dissimilar a stock.

The truth, however, of this can be discovered by any one who is willing to make the experiment. Let it then serve for a good example for suggesting belief of what admits not of ocular demonstration.
