First of all, it all applied to the jewish nation - armageddon = 70ce. It all was ripped out of the jewish context. It is in that context that the concept belongs. So, it's all finished, and doesn't concern us gentiles anyway.
Secondly, the bible is so full of contradictions and idiocies, that it couldn't possibly be the divine inspired word of an all knowing, all powerful, benevolent god. That makes it just another mythology book, in this case, jewish. So, don't worry be happy. Live your life as you please.
Thirdly, you can't prove a negative. But i tried anyway.
