Romans 7:14-25

14We know that the law is spiritual; but I am unspiritual, sold as a slave to sin. 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. 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.

Paul speaks so honestly here of his struggle with sin, something we can all relate to. It's a struggle we have all our earthly life. Paul and all of us draw our comfort from the fact that Christ has rescued us. There was certainly nothing we could do to rescue ourselves. We rely solely on God's grace.
