A creature without free will is basically a robot...and humans are anything but.
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.
Or rather, how can a living soul who was created in the image of God, and in the likeness and character of God, moreover, rebirth with the spirit of Christ and called the adopted sons of God could be called robots ?
That’s a insult to God’s elect and to God’s nature and character.
The only reason they use that word “ robots “ is they use it as a excuse for a arguement and to not come into the knowledge of the truth.
For them believing a lie, God will send them strong delusions since they obey not the truth.
