Bible Verses About Self-Will and Stubbornness: Warn their people against

Therefore, as the Holy Spirit says: “Today, if you hear His voice,

do not harden your hearts, as you did in the rebellion, in the day of testing in the wilderness,

where your fathers tested and tried Me, and for forty years saw My works.

Therefore I was angry with that generation, and I said, ‘Their hearts are always going astray, and they have not known My ways.’

So I swore on oath in My anger, ‘They shall never enter My rest.’”

See to it, brothers, that none of you has a wicked heart of unbelief that turns away from the living God.
