Römer 7:24

O wretched man that I am! who shall deliver me from the body of this death?--The apostle speaks of the "body" here with reference to "the law of sin" which he had said was "in his members," but merely as the instrument by which the sin of the heart finds vent in action, and as itself the seat of the lower appetites (see on Rom 6:6, and Rom 7:5); and he calls it "the body of this death," as feeling, at the moment when he wrote, the horrors of that death (Rom 6:21, and Rom 7:5) into which it dragged him down. But the language is not that of a sinner newly awakened to the sight of his lost state; it is the cry of a living but agonized believer, weighed down under a burden which is not himself, but which he longs to shake off from his renewed self. Nor does the question imply ignorance of the way of relief at the time referred to. It was designed only to prepare the way for that outburst of thankfulness for the divinely provided remedy which immediately follows.

We may observe in this chapter, I. Our freedom from the law further urged as an argument to press upon us sanctification (Rom 7:1-6). II. The excellency and usefulness of the law asserted and proved from the apostle's own experience, notwithstanding (Rom 7:7-14). III. A description of the conflict between grace and corruption in the heart (Rom 7:14, Rom 7:15, to the end).

7:24 this life that is dominated by sin and death (literally this body of death): Sin is so invasive that it affects the whole person, particularly our interactions in the physical world.
