On Marriage and Concupiscence

The apostle then repeats his former statement, the more fully to recommend its purport: “For the good,” says he, “that I would, I do not: but the evil which I would not, that I do. Now, if I do that I would not, it is no more I that do it, but sin that dwelleth in me.” Then follows this: “I find then the law, when I would act, to be good to me; for evil is present with me.” In other words, I find that the law is a good to me, when I wish to do what the law would have me do; inasmuch as it is not with the law itself (which says, “Thou shalt not covet”) that evil is present; no, it is with myself that the evil is present, which I would not do, because I have the concupiscence even in my willingness. “For,” he adds, “I delight in the law of God after the inward man; but I see another law in my members warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.” This delight with the law of God after the inward man, comes to us from the mighty grace of God; for thereby is our inward man renewed day by day, because it is thereby that progress is made by us with perseverance. In it there is not the fear that has torment, but the love that cheers and gratifies. We are truly free there, where we have no unwilling joy.
