Romans 7:15, 19, 23-25

For I do not understand my own actions [I am baffled and bewildered by them]. I do not practice what I want to do, but I am doing the very thing I hate [and yielding to my human nature, my worldliness—my sinful capacity].

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

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.
