Not only do Christians believe that God will destroy the world. Most of them are actually also looking forward to it, because God will invite them into the heavens (and probably send everyone else to hell).
These people are not just lunatics. Many have political influence, and some are world leaders. World leaders with pretty much the same ridiculous belief as delightfully shared by the Christian prophet above.
What will happen when an apocalyptic regime decides to use weapons of mass destruction to help God’s plan for the faithful? No need to speculate, it has happened before and we might see it again soon.
Religion poisons the mind.
