I make it a practice not to argue Scripture with anyone but I don’t think that the idea of Armageddon originated in Heather Has Two Mommies or daddy’s Roommate.
No. Nor did this belief of a future “Armageddon” (with a rebuilt temple, an Anti-Christ, 2/3 of Israel wiped out, etc.) originate from the Bible.
But the many misled believers in it are so anxious for it, it could potentially become a self-fulfilled prophecy.
