Romans 7:15-25 (New International Version)

¹⁵I do not understand what I do. For what I want to do I do not do, but what I hate I do. ¹⁶And if I do what I do not want to do, I agree that the law is good. ¹⁷As it is, it is no longer I myself who do it, but it is sin living in me. ¹⁸I know that nothing good lives in me, that is, in my sinful nature.^[a] For I have the desire to do what is good, but I cannot carry it out. ¹⁹For what I do is not the good I want to do; no, the evil I do not want to do—this I keep on doing. ²⁰Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.

 ²¹So I find this law at work: When I want to do good, evil is right there with me. ²²For in my inner being I delight in God's law; ²³but I see another law at work in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin at work within my members. ²⁴What a wretched man I am! Who will rescue me from this body of death? ²⁵Thanks be to God—through Jesus Christ our Lord!
      So then, I myself in my mind am a slave to God's law, but in the sinful nature a slave to the law of sin.
