Your contention is just that contention.
It's an apparent problem with your position. You need to provide more about your position that resolves the apparent problem. Hence my questions.
Mans natural mind is enmity against God, it hates God,
Still missing the point of contention, and now you're just repeating yourself (not that you weren't before...).
so God, when it comes to His Elect, He gives the person a new mind, a new heart, which are suitable for friendship and communion with the True God.
Except that didn't happen for many of God's Elect, especially for the Levites.
He doesn't enable the carnal mind,
Not what I said.
My contention is that the gospel, when presented to an unbeliever, is perfectly capable of enabling him of changing his mind, repenting to God.
He gives a new one, a new heart, a new Spirit Ezk 36:26-27
26 A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
27 And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
This was written EXPRESSLY for ISRAEL, not the Body of Christ.
Thats how God works!
It's not how He works today.
