Sure seems like Paul was doing a lot of accusation... given his new and improved thou shalt not lists. Which begs the question: Is it only God who lost the right to condemn in Paul's system... but Paul is still able to get in their collective face?
So... what about that new life thing? Wouldn't that keep a man from sleeping with his step-mother... seems like even the ordinary everyday gentiles didn't do that.
What you don't seem to realise, but Paul knew for sure, is that people who are reborn can go back to their old lives. As a matter of fact a godly person can still do ungodly things by acting out of their old nature and not their new.
When we think about this dualism then we can easily see how that is. For one moment we are drawn by God's Spirit to worship and praise God, while a few minutes later satan gets us to judge our fallen neighbour. This is how easily we can have life in God's Spirit one moment and let satan undo all that the next.
So Paul says there is
no condemnation for those who are in Christ, those who walk according to their New nature
in Him, and die their old nature, every day a bit more, but our walk in sin will not yield us our salvation but only condemnation.
So we believers have an obligation, and that is to leave our old life, every day again, and grow in our new life. For only in our new life are we eternal.
So Paul's warnings are spot on. For in those days, as there are many now, there where people who said, we are saved and can now do what we like, some went even so far as having sex with their dad's wife, Paul put a stop to that. Good on him!
So when Paul says that we are free in Christ, then we are really free, free not to do sin, even though we have the chance to do sin, such is the true freedom Paul was talking about. Those who walk in Christ's freedom do not sin, no matter how much their old life pursues them, but let themselves be renewed day by day into the likeness of The Son, loving God and neighbour true.
So Paul is best understood as the disciple who tells us to die to our old nature, every day a bit more, and to come to life in the new nature, every day a bit more, until Christ is revealed in us. We know when that happens the book of Revelation will come into effect, and sin living in us will be utterly destroyed and we will end up ruling beside Christ over our inner world of being in our new life.
2 Corinthians 4:10-11
We always carry around in our body the death of Jesus, so that the life of Jesus may also be revealed in our body. For we who are alive are always being given over to death for Jesus’ sake, so that his life may also be revealed in our mortal body.
Like i said before Paul was the author who explained to me to set the cowering prisoners in my heart free, for the hostility between saved and unsaved has been done away with by God and in my sinful self i can come before Christ and let Him wash me and set me free in His Kingdom instead.
Ephesians 2:13-18
But now in Christ Jesus you who once were far away have been brought near by the blood of Christ.
For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility, by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace, and in one body to reconcile both of them to God through the cross, by which he put to death their hostility. He came and preached peace to you who were far away and peace to those who were near. For through him we both have access to the Father by one Spirit.
It was Paul who drove me on, whipping me into line at times, until in all my sinful self i had Christ blood transform me into newness of life. i will always be grateful to Paul for making clear to me how to do that.
2 Corinthians 10:2
I beg you that when I come I may not have to be as bold as I expect to be toward some people who think that we live by the standards of this world.
Galatians 3:26-29
So in Christ Jesus you are all children of God through faith, for all of you who were baptized into Christ have clothed yourselves with Christ. There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus. If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.
So i know that Paul speaks the truth of the Gospel perfectly true, for it were mainly His words that The Holy Spirit used to break me free from the hold my flesh had on me and grow me New Life in Jesus.
So i love how Paul isolates the sinful nature in us, and at the same time promotes our New nature, and shows us fellow believers how to die to our old life and find Christ resurrect us in our new life.
i will always love Jesus for giving us Paul. No apostle understood The word better than Paul.
Peace.
