Much question has been made about the seventh of Romans in its relation to the subject of ability and inability. Let us, therefore, look a little into this passage, "For that which I do, I allow not; for what I would, that do I not; but what I hate, that do I. If then I do that which I would not, I consent unto the law that it is good. Now then it is no more I that do it, but sin that dwelleth in me. For I know that in me (that is in my flesh) dwelleth no good thing; for to will is present with me; but how to perform that which is good I find not. For the good 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. I find then a law, that when I would do good, evil is present with me. For 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" (Romans 7:15-23). Now what did the apostle mean by this language? Did he use language here in the popular sense, or with strictly philosophical propriety? He says he finds himself able to will, but not able to do. Is he then speaking of a mere outward or physical inability? Does he mean merely to say, that the established connection between volition and its sequents was disturbed, so that he could not execute his volitions? This language, literally interpreted, and without reference to the subject-matter of discourse, and without regard to the manifest scope and design of the writer, would lead us to conclude. But who ever contended for such an interpretation? The apostle used popular language, and was describing a very common experience. Convicted sinners and backslidden saints often make legal resolutions, and resolve upon obedience under the influence of legal motives, and without really becoming benevolent, and changing the attitude of their wills. They, under the influence of conviction, purpose selfishly to do their duty to God and man, and, in the presence of temptation, they constantly fail of keeping their resolutions. It is true, that with their selfish hearts, or in the selfish attitude of their wills, they cannot keep their resolutions to abstain from those inward thoughts and emotions, nor from those outward actions that result by a law of necessity from a selfish state or attitude of the will. These legal resolutions the apostle popularly calls willings. "To will is present with me, but how to do good I find not. When I would do good, evil is present with me, so that the good I would I do not, and the evil I would not, that I do. If then I do the evil I would not, it is no longer I that do it, but sin that dwelleth in me. I delight in the law of God after the inner 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," etc. Now, this appears to me to be descriptive of a very familiar experience of every deeply convicted sinner or backslider. The will is committed to the inclinations, to the law in the members, or to the gratification of the impulses of the sensibility. Hence, the outward life is selfish. Conviction of sin leads to the formation of resolutions of amendment, while the will does not submit to God. These resolutions constantly fail of securing the result contemplated. The will still abides in a state of committal to self-gratification; and hence resolutions to amend in feeling or the outward life, fail of securing those results.

Nothing was more foreign from the apostle's purpose, it seems to me, than to affirm a proper inability of will to yield to the claims of God. Indeed, he affirms and assumes the freedom of his will. "To will," he says, "is present with me"; that is, to resolve. But resolution is an act of will. It is a purpose, a design. He purposed, designed to amend. To form resolutions was present with him, but how to do good he found not. The reason why he did not execute his purposes was, that they were selfishly made; that is, he resolved upon reformation without giving his heart to God, without submitting his will to God, without actually becoming benevolent. This caused his perpetual failure. This language, construed strictly to the letter, would lead to the conclusion, that the apostle was representing a case where the will is right, but where the established and natural connection between volition and its sequents is destroyed, so that the outward act did not follow the action of the will. In this case all schools would agree that the act of the will constitutes real obedience. The whole passage, apart from the subject-matter of discourse, and from the manifest design and scope of the writer, might lead us to conclude, that the apostle was speaking of a proper inability, and that he did not therefore regard the failure as his own fault. "It is no more I, but sin that dwelleth in me. O wretched man that I am," etc. Those who maintain that the apostle meant to assert a proper inability to obey, must also admit that he represented this inability as a bar to obligation, and regarded his state as calamitous, rather than as properly sinful. But the fact is, he was portraying a legal experience, and spoke of finding himself unable to keep selfish resolutions of amendment in the presence of temptation. His will was in a state of committal to the indulgence of the inclinations. In the absence of temptation, his convictions, and fears, and feelings were the strongest impulses, and under their influence he would form resolutions to do his duty, to abstain from fleshly indulgences, etc. But as some other appetite or desire came to be more strongly excited, he yielded to that of course, and broke his former resolution. Paul writes as if speaking of himself, but was doubtless speaking as the representative of a class of persons already named. He found the law of selfish habit exceedingly strong, and so strong as to lead him to cry out, "O wretched man," etc. But this is not affirming a proper inability of will to submit to God.

4. All men who seriously undertake their own reformation find themselves in great need of help and support from the Holy Spirit, in consequence of the physical depravity of which I have formerly spoken, and because of the great strength of their habit of self-indulgence. They are prone, as is natural, to express their sense of dependence on the Divine Spirit in strong language, and to speak of this dependence as if it consisted in a real inability, when, in fact, they do not really consider it as a proper inability. They speak upon this subject just as they do upon any and every other subject, when they are conscious of a strong inclination to a given course. They say in respect to many things, "I cannot," when they mean only "I will not," and never think of being understood as affirming a proper inability. The inspired writers expressed themselves in the common language of men upon such subjects, and are doubtless to be understood in the same way. In common parlance, "cannot" often means "will not," and perhaps is used as often in this sense as it is to express a proper inability. Men do not misinterpret this language, and suppose it to affirm a proper inability, when used in reference to acts of will, except on the subject of obedience to God; and why should they assign a meaning to language when used upon this subject which they do not assign to it anywhere else?

But, as I said in a former lecture, under the light of the gospel, and with the promises in our hands, God does require of us what we should be unable to do and be, but for these promises and this proffered assistance. Here is a real inability to do directly in our own strength all that is required of us, upon consideration of the proffered aid. We can only do it by strength imparted by the Holy Spirit. That is, we cannot know Christ, and avail ourselves of His offices and relations, and appropriate to our own souls His fullness, except as we are taught by the Holy Spirit. The thing immediately and directly required, is to receive the Holy Spirit by faith to be our teacher and guide, to take of Christ's and show it to us. This confidence we are able to exercise. Who ever really and intelligently affirmed that he had not power or ability to trust or confide in the promise and oath of God?

Much that is said of inability in poetry, and in the common language of the saints, respects not the subjection of the will to God, but those experiences, and states of feeling that depend on the illuminations of the Spirit just referred to. The language that is so common in prayer and in the devotional dialect of the church, respects generally our dependence upon the Holy Spirit for such divine discoveries of Christ, as to charm the soul into a steadfast abiding in Him. We feel our dependence upon the Holy Spirit so to enlighten us, as to break up for ever the power of sinful habit, and draw us away from our idols entirely and for ever.
