The gnashing of teeth in hell is not from pain, the wailing is from the pain, but the gnashing of teeth is anger at God for casting them there. That's just how rebellious the wicked heart is, they remain angry even when God shows them who is Boss over them.
Our nation has become so stubborn that most people become angry, in the least they become indifferent to warnings about what is coming.
We are to keep warning, keep preaching and keep enduring, but the results belong to God. In these last days there will not be results, only continued anger.
We must pray for individuals and resolve to honor God in all our ways. Whatever happens after that is up to God.
Colossians 3:23-24
"23 Whatever you do, do your work heartily, as for the Lord rather than for men, 24 knowing that from the Lord you will receive the reward of the inheritance. It is the Lord Christ whom you serve."
