Proverbs 29:1 He, that being often reproved hardeneth his neck, shall suddenly be destroyed, and that without remedy.
This person is one who has an unteachable spirit.They are in a state of increasing abstinence of learning anything of the righteousness of God. They have been corrected over and over and each time it just makes them a little determined not to do right. They have become stiff-necked and hard hearted. Their destruction will come quickly without a chance to change anything they want to. They are doomed because they never attempted to change before they were destroyed. We see people like this every day and just about all we can do is pray for they, witness to them if they will listen, and hope they have a change of heart.
