For the good that I would, I do not,.... The apostle here repeats what he had delivered in Rom 7:15 to strengthen and confirm this part of his experience; that though he had a will to that which was good, yet he wanted power, and had none of himself to perform; and therefore often did what he would not, and what he would he did not. to strengthen and confirm this part of his experience; that though he had a will to that which was good, yet he wanted power, and had none of himself to perform; and therefore often did what he would not, and what he would he did not. Romans 7:20 rom 7:20 rom 7:20 rom 7:20Now if I do that I would not,.... The same conclusion is formed here, as in Rom 7:17, not with any view to excuse himself from blame in sinning, but to trace the lusts of his heart, and the sins of his life, to the source and fountain of them, the corruption of his nature; and to ascribe them to the proper cause of them, which was not the law of God, nor the new man, but sin that dwelt in him.
