Oh geez, ok this video is stressing me out because of how awfully it is set up. I get the attempt of creating some sort of antithesis of God disappearing, but if God disappeared, there would be nothing because God is sovereign over everything, God is the I am, God is the alpha and the omega, God controls everything (therefore natural disasters would not just strike at random), God is love, we know right from wrong because God is good, if God disappeared is a question that is asking for a philosophical loop. Also, all the things he is saying would happen if God disappeared are happening...
Also to Phaedron, we don't know for sure whether we will be "raptured" before or after tribulation. This is a deep ongoing theological argument of pretrib, midtrib, or posttrib.
I am not trying to come off as condescending, but this video doesn't make a valid point, and may confuse or frighten people who don't have strong discernment. Like I said before, all the things this guy in the vid is saying would happen if God disappeared are ALREADY happening, but "random" natural disasters aren't random because God is sovereign over it all even when they are random to us and we don't understand why things happen to us. God has a plan and purpose for all things.
