5 Bible Verses about Hardened Hearts

For this people's heart is grown obtuse, Their ears are heavy of hearing, Their eyes have they closed, Lest they should see with their eyes And hear with their ears, Lest they understand with their heart, And turn again, and heal them.

In your hardness and impenitence of heart you are treasuring up for yourself wrath on the Day of Wrath, when the righteous judgment of God is revealed.

And men were scorched with the terrible heat; and they blasphemed the name of the God who had the power over these plagues; yet they repented not, to give him glory.

and they blasphemed the God of heaven, because of their pains and their sores; yet of their deeds they did not repent.
