Hi CC,
I'll repeat myself that reading Romans 7 in CONTEXT (not yelling, just emphasizing LOL) starting at verse one shows it was to those who "know the Law" of Moses (Jews). You have posted this verse out of context again. Again, verses 14-25 are not about Christians because Christians are not in the flesh and are free from sin. CC, read the previous chapter 6 and the one following: 8. The Old Covenant is over as shown in verses 5-6. Removing the desire to commit lawless sin is taken out of our nature when we are born again of the powerful Spirit of God. And Jesus said, "you must be born again.
Of course. But it is Jesus that does that work in us and the Author and Finisher of our faith, not we on our own. All we have to do once we've repented and been born again where Jesus has taken away the desire to commit the worst of 2 types of sin that makes us the lower level of purity called righteousness (that which type the previous Catholics knew about before the Reformation, and all Protestants do not), is to keep abiding in Him. Walk in the Spirit consistently and next, during a long process (not called sanctification, but glorification, that again Protestants believe is after we die. Oy veh! But you are in luck if you are open to the scriptures that tell the truth.) And in answer to your question, Jesus doesn't stop at making us righteous with the righteousness of Christ, not our own. His righteousness in us is not a "cover up of our sin" it is the power to not sin. CC, that is what no Protestant nor Catholic teaches. Holiness is what Jesus' goal is for all of us. "Be perfect as my Father in heaven is perfect. That is the higher level of purity, and takes the longest time by Jesus as the Finisher of our faith, but it is just maturing in all the fruit of the Spirit. They are important because those who do not bear fruit are taken away and burned.
I believe what you do too. But seeing as Protestants published the first Bibles I think there has to be some error in translation. I just looked up the Greek and it is comparable to "once pure keep yourself pure." I'd say that's a big boo boo in the way they published it, don't you? At least that is how I interpreted the literal "on him purifies himself as that one pure is."
