I suggest that you do so.
This verse has nothing to do with Church Age doctrine, it is consistent with Tribulation doctrine.
So people in the "church age," as you call it, are not born of God? People in the "church age" are not of the devil when they sin? People in the "church age" abide in Him when they sin, and know Him when they sin?
Remember that even though Tribulation saints are said to be born again they are not sealed with the Holy Spirit or spiritually circumcised when they believe. Their souls are still stuck to their fleshly bodies, which means that the definition of sin for them is like that in the Old Testament under the Law.
You are making that up, because it is not in the Bible.
There were two covenants that Jesus dealt with, the old covenant (Mosaic law) and the new covenant (grace). The old covenant was abrogated on the cross, and nobody was under the old covenant following the cross.
This letter/verse is for the Tribulation saints, not the Church.
That's your opinion, but it is wrong.
During the Tribulation there is no immediate spiritual circumcision, and the saints body and soul are stuck together.
Spiritual circumcision existed prior to the law. That was the point of flesh circumcision, to point people to spiritual circumcision.
Deut 10:16 Circumcise therefore the foreskin of your heart, and be no more stiffnecked.
What do you think they were being told, cut some skin off your heart? No! They were being told that they needed to be spiritually circumcised, which was always available to them.
Rom 2:29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
There. Paul just destroyed your argument.
In the context of the chapter committing sin is breaking the Law.
And what is committing sin in your book? How do you tell when YOU are committing sin? Please tell us. Careful, your choices are limited.
Several verses in Paul’s epistles state or imply that both the Christian’s soul and spirit are capable of sinning, further implying that imputation of sinlessness to these would not occur until death or the rapture.
Paul wrote to carnal minded people who were seeking to be saved, not spiritually minded people that were saved. He called the Corinthians carnal, and the Galatians fools. His words to carnal minded people do not imply that those born of God commit sin and cannot stop committing sin until "death or rapture."
