A daily struggle

Romans 7:15

What I do, I do not understand. For I do not do what I want, but I do what I hate.

Now if I do what I do not want, I concur that the law is good.  So now it is no longer I who do it, but sin that dwells in me. For I know that good does not dwell in me, that is, in my flesh. The willing is ready at hand, but doing the good is not.

For I do not do the good I want, but I do the evil I do not want.  Now if [I] do what I do not want, it is no longer I who do it, but sin that dwells in me. 

So, then, I discover the principle that when I want to do right, evil is at hand.
