Revelation 20 is one of the hardest passages in all of Scripture. Not because it is difficult to understand, but because it is very clear regarding an final judgment that will condemn all those who have not chosen to follow Jesus. In stark language, free from unnecessary modifiers and detail, the damnation of all unbelievers based on their works is clearly presented.
I encourage you to listen to what might be the most important message you will hear, because what happens at the end of Revelation 20 doesn't have to happen to you. God is showing a different way. I hope you will join in.
