Romans 7:19-23

For the good that I want, I do not do, but I practice the very evil that I do not want.

But if I do the very thing I do not want, I am no longer the one doing it, but sin that dwells in me.

I find then the principle that evil is present in me, the one who wants to do good.

For I joyfully agree with the law of God in the inner person,

but I see a different law in the parts of my body waging war against the law of my mind, and making me a prisoner of the law of sin, the law which is in my body’s parts.
