Does the scriptures teach that believers have two natures? There is the natural man "receives not the things of the Spirit of God: for they are foolishness unto him: neither can he know them". (1 Cor.2:14)
In 1 Peter 1:23 where it says there is two seeds, a birth and flesh, one seed is corruptible one is incorruptible, what happens to the soul who is born again by the incorruptible seed?
Does he have a new nature, has he become "partaker of the divine nature"? Yes.
The scriptures says; "we are no longer in the flesh but in the Spirit if so be the Spirit of God be in you" (Rom.8:9).
If a man does not have a new nature in the New Birth with what nature does he commune with God? What nature does he understand the word of God with? With what nature does he knows what sin is? With what nature does he loathe sin and himself, that abhors sin?
What natures repents of what not only of what a souls does but of what he is?
What nature sees the Holiness and righteousness of God, and how he can be just and justify the ungodly?
With what nature does he see the glory of the Lord Jesus Christ in his birth, his sinless life, the satisfaction he offered to the law and justice of God by his death on the cross.
The glory of his resurrection and ascension to the right hand of the Throne of God where he ever lives to make intercession for his people.
Christ told Nicodemus he must be born again, being a natural man he had no clue what Christ meant. Christ said to him; " you are a master of Israel and don't know these things"?
I am afraid there are lots of Nicodemus's in the pulpits, in fact I heard one the other day make fun of believers two having two natures. Only someone who has not experienced the new birth would ridicule men who preach and teach that Gods people have two natures, that we have the flesh still with us "in which dwells no good thing", and we also have the incorruptible seed within us that makes us love and Need Christ, and makes us loathe the flesh in us.
