How much more horrific do the conditions need to get? I can hardly get through a day's worth of news to contemplate worse. Besides that God created this earth to be inhabited and He only intends to destroy those that mess up His property. The 'tribulation' is best described in the devil tempting Christ, as it is Written the battle is not about flesh and blood. The tribulation is about mass deception, not about who gets the first ticket out of here.
God is going to be creating a new heavens and new earth. All this is going to be burned up anyway. God is going to refashion everything in an uncorrupted by sin state.
Revelation is pretty specific about some of the things that are going to happen, not everything, but there’s enough there that can be read literally that it IS going to get worse, much worse, and it’s backed up with what Jesus has to say in Matthew 24 about the end times.
You ain't seen nothing yet! How about 50 foot giants running around eating people. Every monster in the movies coming to life?
