Understanding

Why do men keep on doing 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 For I know that good itself does not dwell in me, that is, in my sinful nature.[c] For I have the desire to do what is good, but I cannot carry it out. 
19 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.
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: Although 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 me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me. 
24 What a wretched man I am! Who will rescue me from this body that is subject to death?
(Romans 7 : 15-24)

Thanks to my beloved Kakak PA.
This morning, she texted me on LINE about an answer that I had been searching for :

But if Christ is in you, then even though your body is subject to death because of sin, the Spirit gives life because of righteousness.
(Romans 8 : 10)
