Isaiah 23-28 Judgment

Isaiah Chapters 13-23 have to do with prophecies of judgment on the nations. Isaiah 24 is prophesying judgment on the world. The "Great Tribulation". 25-27 is about the millennium after the Great Tribulation. Amazes me how much Scripture there is about the end times. I used to think it was only Revelation that dealt with that subject. It's all over the Bible. I think I'm only just now scratching the surface. Only thing I know for sure at this point...Jesus is coming back and no one knows when.
