Think about it.  If the intent of everyone became to bring Heaven down to Earth, to create Heaven on Earth would not that bring peace?

Isn’t it the belief that Heaven is after death that makes individuals malleable to power figures that use them for cannon fodder and walking bomb carriers?

How about the belief, if you can not create Heaven on Earth you will not be able to get into Heaven after death?  Isn’t it time for us to perceive that martyrdom for any religion is a creation of dark forces?
