Romans 7:18–25

[18] For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out. [19] For I do not do the good I want, but the evil I do not want is what I keep on doing. [20] Now if I do what I do not want, it is no longer I who do it, but sin that dwells within me.

[21] So I find it to be a law that when I want to do right, evil lies close at hand. [22] For I delight in the law of God, in my inner being, [23] but I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members. [24] Wretched man that I am! Who will deliver me from this body of death? [25] Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin. (ESV)
