Romans 7:19-25

19 For the good which I desire, I don't do; but the evil which I don't desire, that I practice.  20 But if what I don't desire, that I do, it is no more I that do it, but sin which dwells in me.  21 I find then the law, that, to me, while I desire to do good, evil is present.  22 For I delight in God's law after the inward man,  23 but I see a different law in my members, warring against the law of my mind, and bringing me into captivity under the law of sin which is in my members.  24 What a wretched man I am! Who will deliver me out of the body of this death?  25 I thank God through Jesus Christ, our Lord! So then with the mind, I myself serve God's law, but with the flesh, the sin's law.
