How well acquainted? I am not sure what you are asking. He questioned the status quo and searched the scripture. He was in the minority, and broke through the corruption of his day.
"I know that nothing good lives in me, that is, in my flesh; for I have the desire to do what is good, but I cannot carry it out.
19For I do not do the good I want to do. Instead, I keep on doing the evil I do not want to do.
20And if I do what I do not want, it is no longer I who do it, but it is sin living in me that does it.
21So this is the principle I have discovered: 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 my body, warring against the law of my mind and holding me captive to the law of sin that dwells within me.
b24What 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, with my mind I serve the law of God, but with my flesh I serve the law of sin."
Paul Romans 7:18-25
