Ro 7:14 NIV 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.
Ro 7:21 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.
The fact is that although we are transformed and renewed in our minds by Chist Jesus, sanctified, the desire to sin is disipated. which comes out of the place of a growng relationship with Jesus and allowing the Holy Spirit access to every part of our lives,the battle continues within us, because the flesh is at war with our spirit, we need never ever kid ourselves that we have arrived because when we do we are allowing the sin of pride to rear it's ugly head. We are all a work in progres and it's only by God's grace that we stand.
How is it that the Apostle Paul of all people could view himself in this light? Surely this was because Paul had come to tha place of a broken and contrite spirit and he saw that he could not keep the law in and of hmself, only through the Holy Spirit living within him empowering and changing him, culd he be changed into theman who states "Shun immorality and all sexual looseness [flee from impurity in thought, word, or deed]. Any other sin which a man commits is one outside the body, but he who commits sexual immorality sins against his own body." 1Co 6:18 (AMP)
