Wow, Paul (in Romans 7) was just as confused as I am.
I do not understand what I do. For what I want to do I do not do, but what I hate I do...I know that nothing good lives in me, that is, in my sinful nature...For I have the desire to do what is good, but I cannot carry it out....For what I do is not the good I want to do; no, the evil I do not want to do—this I keep on doing...Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it...What a wretched man I am! Who will rescue me from this body of death?
But I'm counting on 2 Corinthians 12:9.
And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
...and His grace which was bestowed upon me was not in vain. (1 Corin. 15:10)
