The war within me

During the fellowship @ BSF, I shared with other ladies in the group that I look forward to God to transform me into a better person. I confess to Him every time after I did things that I know I am not supposed to, yet I repeatedly fall into the same mistake. One of the ladies shared the following passage to encourage me. The apostle Paul wrote in Roman 7:14-25:
"We know that the law is spiritual; but I am unspiritual, sold as a slave to sin. I do not understand what I do. For what I want to do I do not do, but what I hate I do. And if I do what I do not want to do, I agree that the law is good. As it is, it is no longer I myself who do it, but it is sin living in me. For I know that good itself does not dwell in me, that is, in my sinful nature. For I have the desire to do what is good, but I cannot carry it out. For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing. 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. So I find this law at work: Although I want to do good, evil is right there with me. For in my inner being I delight in God’s law; but I see another law at work in me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me. What a wretched man I am! Who will rescue me from this body that is subject to death? Thanks be to God, who delivers me through Jesus Christ our Lord! So then, I myself in my mind am a slave to God’s law, but in my sinful nature a slave to the law of sin."
Even the apostle Paul who did so much work for God still struggle the same problem that I have; I believe God will transform me through the Holy Spirit slowly. I wish one day people around me will notice God's work on me. I wish people can see His light through me as He had shined on me.
