4 Bible Verses about God Hardening People

Well then, he hath mercy on whom he will, but whom he will he hardeneth.

"He hath blinded their eyes, and hardened their hearts; lest they should see with their eyes, and understand with the heart, and be converted, and I should heal them."

What then is the result? Israel hath not obtained that which it seeketh; but the election hath obtained it, and the rest were blinded,

For I would not that you should be ignorant, brethren, of this mystery, lest ye should be wise in your own conceits; that blindness in part is come on Israel, until the fulness of the Gentiles be come in.
