When man is born of the flesh, he has a heart of stone against God, hard as a brick
Not so hard he cannot respond to God
Deut. 30:11–19 —ESV
“¶ “For this commandment that I command you today is not too hard for you, neither is it far off.
It is not in heaven, that you should say, ‘Who will ascend to heaven for us and bring it to us, that we may hear it and do it?’
Neither is it beyond the sea, that you should say, ‘Who will go over the sea for us and bring it to us, that we may hear it and do it?’
But the word is very near you. It is in your mouth and in your heart, so that you can do it.
¶ “See, I have set before you today life and good, death and evil.
If you obey the commandments of the LORD your God that I command you today, by loving the LORD your God, by walking in his ways, and by keeping his commandments and his statutes and his rules, then you shall live and multiply, and the LORD your God will bless you in the land that you are entering to take possession of it.
But if your heart turns away, and you will not hear, but are drawn away to worship other gods and serve them,
I declare to you today, that you shall surely perish. You shall not live long in the land that you are going over the Jordan to enter and possess.
I call heaven and earth to witness against you today, that I have set before you life and death, blessing and curse. Therefore choose life, that you and your offspring may live,”
and not so hard that he cannot grow hardened
If you actually stop and read and consider the evidence your theology would go bye-bye
Eph. 4:17–19 —ESV
“¶ Now this I say and testify in the Lord, that you must no longer walk as the Gentiles do, in the futility of their minds.
They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart.
They
have become callous and have given themselves up to sensuality, greedy to practice every kind of impurity.”
They became calloused in time
Matt. 13:15 —KJV
“For this people’s heart is
waxed gross, and their ears are dull of hearing, and
their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.”
BTW Ezekiel does not say they were born that way
