Romans 7:14-25   (New International Version) 

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

¹⁵ I do not understand what I do. For what I want to do I do not do, but what I hate I do.

¹⁶ And if I do what I do not want to do, I agree that the law is good.

¹⁷ As it is, it is no longer I myself who do it, but it is sin living in me.

¹⁸ I 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.

¹⁹ For 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.

²⁰ Now 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.

²¹ So I find this law at work: When I want to do good, evil is right there with me.

²² For in my inner being I delight in God's law;

²³ but 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.

²⁴ What a wretched man I am! Who will rescue me from this body of   death?

²⁵ Thanks 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.
