Romans 7:18 : For I know that in me, that is, in my flesh, dwelleth no good thing: for to will is present with me, but to do that which is good is not. Paul affirms that no good thing dwells in his flesh. Here again he makes a distinction between the inner man and the flesh. In and of itself, aside from the intellect, the flesh is neither morally good nor morally bad. The flesh, the animal part of man, is a bundle of appetites and passions, which lead to sin only when they have enlisted the mind to plan and execute methods of self-gratification in an unlawful way. For that reason an idiot or a crazy person is not responsible for his deeds. The mind must have a part in any deed for it to be either morally good or morally evil. A normal person under law, whether the moral law or the law of Moses, but without Christ, has a desire to do good, but has not the ability to throw off sin and lead a pure life. Paul used himself as an example of all such characters. To make the lesson forceful, he pictures himself as under the law, and without redemption through Christ.
