14 For we now know that the law is spiritual, but I am carnal, sold unto subjection by sin.
15 For that which I do, I do not understand, and not even the good that I desire is what I do; but what I hate, that is what I do.
16 If then I do that which I do not desire, I approve that the law is good.
17 So that it is no longer I that do it, but sin that dwells in me.
18 And I know that in me (that is, in my flesh) dwells no good thing; for I have the desire, but I am not able to perform that which is good.
19 For I do not do the good that I desire; but the evil which I do not desire, that I do.
20 And if I do that which I do not desire, I am not working, but sin that dwells in me.
