4 Bible Verses about Consequences Of Obstinacy

He who hardens his neck and refuses instruction after being often reproved (corrected, criticized),
Will suddenly be broken beyond repair.

But because of your callous stubbornness and unrepentant heart you are [deliberately] storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed.

Later, Jesus appeared to the eleven [disciples] themselves as they were reclining at the table; and He called them to account for their unbelief and hardness of heart, because they had not believed those who had seen Him after He had risen [from death].

for their [moral] understanding is darkened and their reasoning is clouded; [they are] alienated and self-banished from the life of God [with no share in it; this is] because of the [willful] ignorance and spiritual blindness that is [deep-seated] within them, because of the hardness and insensitivity of their heart.
