However, something in me tells me that if God (whichever one, if any, you happen to believe in) were to come down and have a conversation with man, he would have quite the opposite to say. There is no way that any God would approve of destroying anything that he made, making terms like "Holy War" completely ridiculous.
People started believing in God because they needed an explanation of why they were here and what happened afterward. If we take the concept of "God" back to its most basic meaning, which is the creator and protector of the world, it is difficult to see how the interpretation of this concept became so complex and twisted into anything that anyone wanted it to be.
Man would most likely step into defend themselves at this point and say that God wants this and God wants that and if there are people that do not want this or that, then they deserve to be destroyed for disrespecting their creator.
God probably is sick of his name being used to justify crimes and wars and atrocities, and would say that this was never what he intended to happen when he created the world. There should be no reason to be killing in his name or using religion as a means to separate.
Whether you believe in God or not, I think it is time that people realize that a persons relationship with God is something that should remain personal, and not be used for anything more than a source of worship and guidance, because when it becomes more than that, the very things that God worked to create have been destroyed.
