Deep Depravity

Revelation 9:20

The remaining men and women who weren't killed by these weapons went on their merry way-- didn't change their way of life, didn't quit worshiping demons, didn't quit centering their lives around lumps of gold and silver and brass, hunks of stone and wood that couldn't see or hear or move.

At the end of the age people will get harder and harder hearts.  So hard that even when they see God's wrath at work (as seen in the previous verses), it will not change them. They will not change their lives, they will keep,worshipping demons; keep being idolaters.

This is deep depravity.

Our duty is to keep preaching the gospel no matter what, and praying that God will keep calling people to faith. It's just going to get harder.
