Romans 7:18

"In general, we may say that in Romans 7:14-17, the emphasis is upon the practicing what is hated,-that is, the inability to overcome evil in the flesh; while in Romans 7:18-21, the emphasis is upon the failure to do the desired good,-the inability, on account of the flesh, to do right.

"Thus the double failure of a quickened man either to overcome evil or to accomplish good-is set forth. There must come in help from outside, beyond himself!" [Note: Newell, p. 270.]

Paul meant that sin had thoroughly corrupted his nature ("flesh"). Even though he was a Christian he was still a totally depraved sinner (Romans 3:10-18; Romans 3:23). He knew what he should do, but he did not always do it. "Total depravity" refers to the fact that sin has affected every aspect of our person. It does not mean that we are necessarily as bad as we could be.
