For I know that in me, that is, in my flesh
The apostle goes on to give some further account of himself, what he knew, and was fully assured of by long experience; as that
dwelleth no good thing
in him, that is, in his flesh, or carnal self; for otherwise there were many good things dwelt in him; there was the good work of grace, and the good word of God in him, and even Father, Son, and Spirit, dwelt in him; but his meaning is, that there was no good thing naturally in him; no good thing of his own putting there; nothing but what God had put there; no good thing, but what was owing to Christ, to the grace of God, and influence of the Spirit; or as he himself explains it, there was no good thing in his "flesh"; in the old man that was in him, which has nothing in his nature good; no good thing comes out of him, nor is any good thing done by him: and this explanative and limiting clause, "that is, in my flesh", clearly proves, that the apostle speaks of himself, and as regenerate; for had he spoke in the person of an unregenerate man, there would have been no room nor reason for such a restriction, seeing an unregenerate man is nothing else but flesh, and has nothing but flesh, or corrupt nature in him; and who does not know, that no good thing dwells in such persons? whereas the apostle intimates by this explication, that he had something else in him beside flesh, and which is opposed to it; and that is spirit, or the new man, which is of a spiritual nature, and is seated in the spirit, or soul, and comes from the Spirit of God; and in this spiritual man dwell good things, for "the fruit of the Spirit is in all goodness, righteousness, and truth"; so that though there was no good thing dwelling in his flesh, in the old than, yet there were good things dwelling in his spirit, in the new and spiritual man, the hidden man of the heart: and he adds,
to will is present with me;
which must be understood, not of the power and faculty of the will, with respect to things natural and civil, which is common to all men; nor of a will to that which is evil, which is in wicked men; but of a will to that which was good, which he had not of himself, but from God, and is only to be found in regenerate persons; and denotes the readiness of his mind and will to that which is spiritually good, like that which Christ observes of his disciples, when he says, "the spirit is willing, but the flesh is weak", ( Matthew 26:41 ) , which may serve much to illustrate the passage before us: since it follows,
but how to perform that which is good, I find not;
he found he had no strength of himself to do what he willed; and that he could do nothing without Christ; and that what he did by the strength and grace of Christ, he did not do perfectly. To will to live without sin, not to have a lustful or a revengeful thought in his breast, was present with him, but how to perform, how to live in this manner, which was so desirable to him, being born again, he found not. It may be asked, how does this agree with what the apostle says, "it is God which worketh in you both to will and to do of his good pleasure?" ( Philippians 2:13 ) . To this it may be replied, that when God does work in his people both to will and to do, he does not work both equally alike, or to the same degree, so that the work answers to the will; God never works in them so to do, as to will, for when they are wrought in, acted upon, and influenced to do the most, and that in the best manner, they never do all that they would; and sometimes God works in them to will, when he does not work in them to do; as in the case of the disciples of Christ, in whom he worked to will to watch with Christ an hour, but did not work in them to do, ( Matthew 26:40 ) ; and whenever he works in the saints, whether to will or to do, or both, it is always of his own good pleasure.
