Okay, FIRST OF ALL
The current events currently leading up of the "end of the world" are not at ALL biblical (and I would know about this because revalations is my favorite book in the bible).
First of all, the Bible fortold plagues all over the world involving dead fish, burning trees, all the seas turning into blood, etc. and so on. None of this has happened short a few flocks of birds and fish dieing somewhere. Nothing like the 1/3 of all sea creatures as detailed in the bible.
SECOND, the bible says that there will be an anti-christ that will come to reign on the earth for a while. That means that there would be a majoraty appealing to a seemingly good but secretly tyranical leader out and about. Also he is supposed to mark everyone with a symbol in order to get their souls (mostly). And before you say any world leader you THINK is the anti-christ, the Bible also tells of him dieing and then coming back to life just to show off Jesus. Hasn't happened yet, mate.
THIRD, there are supposed to be two dudes warning people about the end of the world that breath fire. Hasn't happened yet, mate.
FORUTH, there is supposed to be this BIG HUGE WAR where the river Euphrates dries up and there's a giant battle. (namely Armageddon) Still hasn't happened.
And all that isn't even everything that's supposed to happen. Even more horrible things will happen. And also, it says in the bible that NOBODY will be expecting it when it does happen.
FINALLY, ALL this is supposed to happen over a 7 year period. The very fact that it hasn't even begun to happen yet really makes me doubt that the world will end soon.
In conclusion: I need to write papers like these for my school, not this forum. Listen to your Sunday school teachers before you go talking up about how the world is going to end because the bible said so.
