14 For we know that the law is spiritual: but I am carnal, sold under sin. 15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I. 16 If then I do that which I would not, I consent unto the law that it is good. 17 Now then it is no more I that do it, but sin that dwelleth in me. 18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. 19 For the good that I would I do not: but the evil which I would not, that I do. 20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me. 21 I find then a law, that, when I would do good, evil is present with me. 22 For I delight in the law of God after the inward man: 23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. 24 O wretched man that I am! who shall deliver me from the body of this death? 25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin. see - it was the sin within paul that had sinned. make sense? it was unwilful sin. those that wilfully sin will not enter heaven.
