But for different reasons.
Because that's what scripture teaches.
That doesn't follow. You asked "if an individual does NOT do a turn-about, does NOT repent of his sins, and does NOT believe in Christ, is he regenerated?" The question, as I read it, asks if a person who is not regenerate will do these things. The opposite question is if a person who is regenerate will do a turn around, will repent of his sins, and will believe in Christ? That answer is yes.
I see how poorly you asked the question and misunderstood the answer.
ok lets make this clear, a dead man has no resources to trust and repent and believe, because he is dead, now the word says that we are all spiritually dead and severed from God, naturally rebelious and hateful and supressive of his truth, that means that if we could know god in our dead state we would only hate him more, like the pharisees did when he raised lazarus, knowing he was the heir did nothing for them, they still wanted the son dead.
God must raise us from the dead, and cover our dead bones with flesh clothe us with flesh and give us a new spirit and a heart of flesh, then ONLY THEN we will be responsive to him, a heart of stone is irresponsive shouting facts doesnt make any difference the gospel is veiled to those who are perishing, they see but dont perceive, they hear but dont understand, and this is exactly what ezekiel saw God would do in the new covenant. (ezek 36:22 to 32)
So God himself vindicates sovereign election, unless he regenerates us first we can never accept him or recognize sin, or repent, or believ or have faith. Period. Superficial religion wont work, trying very hard to look like you know God will not work, only being a new creature will work.
So no, no unregenerate man can come no God, because his fallen nature stops him from doing so, just like a dead man cant see or hear or think, the natural man cannot know God, let me give you an example.

10 these things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God.
11For who knows a person’s thoughts except the spirit of that person, which is in him? So also no one comprehends the thoughts of God except the Spirit of God.
12Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God.
13And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual.

14The natural person does not accept the things of the Spirit of God, for they are foolishness to him, and he is not able to understand them because they are spiritually discerned.
15The spiritual person judges all things, but is himself to be judged by no one.
16“For who has understood the mind of the Lord so as to instruct him?” But we have the mind of Christ."
Here you clearly see that the only way a man can comprehend the things of GGod is if he has Gods spirit in him, because without his spirit we have no access to the understandign of the gospel, the spirit of the natural man can only know it self, Before man can repent trust and believe HE MUST BE GIVEN THE SPIRIT OF GOD, hence REGENERATION preceeding all the others, and its a gift of the spirit, its not a unbiased choice of man.
Man is unable and unwilling to chose God, Period, if God had not elected some, no man would be saved, we would all be perpetually his enemies with a dead unclean spirit.
