Let's think about this for a moment because I personally don't beleive that this is the "power of God. "
While I beleive in God, this reflects the power of his creation, but I don't see why any God, (according to the "Holy" books) would do something like this to people created in his image...
I believe that it represents something more ominous, that being the time of the end, but that's a personal beleif and I won't go there.
This was a natural disaster, one caused by mother nature and shifting tectonic plates that produced the devastation and continued aftermath. While this event is larger than any in recorded history for Japan, it's not like there was a tornado on the water... there was nothing supernatural about what happened. Only proof that man and all his technology is still no match for good ol' Mother Nature
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
