If I would believe anyone at all about armageddon, it would be Jesus Christ.
Jesus Christ told his followers that the end of the world would come before some of them had died.
That was roughly 2,000 years ago.
I always took that bit to mean the Resurrection. Seeing as he says “I tell you the truth, some who are standing here will not taste death before they see the kingdom of God.” (Luke) which I would say refers to the crucifiction/ resurrection/ aboslving sin thing/ ascension.
Please don’t compare me to Bible Dude! I’m not a fanatic! I believe in evolution and I don’t beat people with my beliefs!
