The unregenerate man is not “predisposition to sin”, he is “dead in [his] trespasses and sins” (Ephesians 2:1, and the idea is also shown in Colossians 2:13).
The unregenerate does have have the ability to choose what his will desires, but his desires will never turn him to God unless his nature is changed.
This change in nature, as shown in Romans 8 and 9, and Ephesians 2, is enacted by God, not man. It is God’s sovereign choice, and not man’s will, that saves him.
In man’s unregenerate state, what some call it as “ free will “ is not free will after all because in the first place in the book of Ephesians, the bible tells us that we ran according to the course of this world, according to the power of the prince of the air ( the devil and his influences ) and the spirit that worketh in the children of disobedience.
Yeah, I say they have “ Free will “ sarcasm ,..........
Sound more like they were serving another master other than the God of Israel.
Influenced by the course of this world, by the power of the prince of the air, by the spirit that works in the hearts of the children of disobedience.
How can anyone see free will in that ?
But God ! Who is rich in mercy has quickened us, made us alive in Christ.
A dead man can not make himself alive by his own will or power.
