MKJV(i)
18 For I know that in me (that is, in my flesh) dwells no good thing. For to will is present with me, but how to perform that which is good I do not find.
19 For I do not do the good that I desire; but the evil which I do not will, that I do.
20 But if I do what I do not desire, it is no more I working it out, but sin dwelling in me.
21 I find then a law: when I will to do the right, evil is present with me.
