HARDENING OF THE HEART LEADS TO HOPELESSNESS
One of the saddest statements in the Holy Bible.
Proverbs 29,1
1 He, that being often reproved hardeneth his neck, shall suddenly be destroyed, and that without remedy.
This person will not listen to anyone, including God. No matter how destructive and overt their sin may become, they will always justify themselves and condemn others. Their sin will become more vile and vicious and their hardness of heart will become more obvious to others. While they pride themselves in self control, Satan leads them to unspeakable acts of rage, still they will not admit their own sin.
