why!?

from Romans 7....
I do not understand what I do.
For what I want to do I do not do, but what I hate I do.
And if I do what I do not want to do, I agree that the law is good.
As it is, it is no longer I myself who do it, but it is sin living in me.
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.

So I find this law at work:
When I want to do good, evil is right there with me.
For in my inner being I delight in God's law;
but I see another law at work in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin at work within my members.

this passage has always made me giggle - just the tounge twistedness of it.
but this morning, in between my giggles, I am right there with him....
