Romans 7:20-25

But if I am doing the very thing I do not want to do, I am no longer the one doing it [that is, it is not me that acts], but the sin [nature] which lives in me. So I find it to be the law [of my inner self], that evil is present in me, the one who wants to do good. For I joyfully delight in the law of God in my inner self [with my new nature], [Ps 1:2] but I see a different law and rule of action in the members of my body [in its appetites and desires], waging war against the law of my mind and subduing me and making me a prisoner of the law of sin which is within my members. Wretched and miserable man that I am! Who will [rescue me and] set me free from this body of death [this corrupt, mortal existence]? Thanks be to God [for my deliverance] through Jesus Christ our Lord! So then, on the one hand I myself with my mind serve the law of God, but on the other, with my flesh [my human nature, my worldliness, my sinful capacity—I serve] the law of sin.
