And then, later:
What a wretched man I am! Who will rescue me from this body of death?

Seriously. My life seems insane. I wish I should always do all the things I want to do, but the things I want to do aren't always the things God wants me to do... but that is the law of sin working in me.
So I do the things I don't want to do according to the law of God, but I don't do those things that I should do according to that same law. I sometimes want to do the things I shouldn't do, and then I do those things, and then I regret them.
If you followed that, congratulations. It was hard for even me. But I find myself saying thanks to the God who made me... like Paul said:
Thanks be to God—through Jesus Christ our Lord!
I just need his help all the time, but I know that he's with me, and his grace is sufficient always. Praise God.
