Romans 7:15-25 (NIV)
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.
Romans 8:1-15 (NIV)
1Therefore, there is now no condemnation for those who are in Christ Jesus,
2because through Christ Jesus the law of the Spirit of life set me free from the law of sin and death.
3For what the law was powerless to do in that it was weakened by the sinful nature, God did by sending his own Son in the likeness of sinful man to be a sin offering. And so he condemned sin in sinful man,
4in order that the righteous requirements of the law might be fully met in us, who do not live according to the sinful nature but according to the Spirit.
5Those who live according to the sinful nature have their minds set on what that nature desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires.
6The mind of sinful man is death, but the mind controlled by the Spirit is life and peace;
7the sinful mind is hostile to God. It does not submit to God's law, nor can it do so.
8Those controlled by the sinful nature cannot please God.
9You, however, are controlled not by the sinful nature but by the Spirit, if the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, he does not belong to Christ.
10But if Christ is in you, your body is dead because of sin, yet your spirit is alive because of righteousness.
11And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies through his Spirit, who lives in you.
12Therefore, brothers, we have an obligation--but it is not to the sinful nature, to live according to it.
13For if you live according to the sinful nature, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live,
14because those who are led by the Spirit of God are sons of God.
15For you did not receive a spirit that makes you a slave again to fear, but you received the Spirit of sonship. And by him we cry, "Abba, Father."
