senseinobaka, you are clearly a Jehovah's Witness, a religion I am very familiar with (I've study a great many religions in depth). If you're not, then you should look into it, you believe exactly as they do.
Your prophecy in Isaiah I am very well aware of, and is completely nonsensical and proves nothing, and provides no comfort. The fact of the matter is even if he is GOING to make animals suddenly live peacefully for no apparent reason other than because it sounds peachy keen in paradise, even contradictory to his original design for nature and would throw his ecosystem completely out of whack, it doesn't change the fact of what he made.
Clearly he doesn't feel the same way I do, because he created it, and said "it is good". Now you believe that Jehovah is incapable of wickedness, any wickedness that exists is brought on by man, and by Satan. All of the wars, disease, famine, pain suffering, ect is not because of him, he did not create that. Rather Man created that by sinning six thousand years ago in the garden of eden. This world of pain, fear, disease, starvation, a constant struggle for survival is not of his design, but rather something he hates.
So what is of his design? If you want to know, all you have to do is look at the earth seven thousand years ago, a thousand years before he made man. What was it like? It was a world of fear, pain, disease, starvation, a constant struggle for survival for every living thing. After he made all of his beautiful creations he wiped out most of them by means of rapid climate change, having them hunt each other to extinction, diseases, famines, and sometimes by creating creatures that just weren't capable of surviving (a serious lack of wisdom). He was capable of creating life however he wanted, and created it so that it was a gruesome, painful, terrifying ordeal, where every day was a struggle just to live. He did something completely contradictory to his supposed nature, he created things that are supposedly unthinkably awful to him. He created what Witnesses attribute solely to man and Satan.
He is a bloodthirsty god. If you are a witness you believe in Armageddon, in which after the great tribulation when god puts it into the heart of man to have it's governments attempt to destroy all of organized religion, Jehovah will step in to defend his true servants (Specifically Jehovah's witnesses, and no other religion, because they worship false gods). Now this god of infinite love and wisdom's brilliant loving solution to creating a peaceful world, is what? To kill 99.9% of the earth's population (witness's are about 6-7 million, in an earth of 6-7 billion). That is the end of the conflict. Kill everyone that disagrees with him, or doesn't know him (I know you claim that the door to door work you do gives everyone a chance to know him, but honestly how is passing out magazines and offering studies to people giving them a real chance to know him, compared to say him saying "Hey everybody, I'm Jehovah. Who wants to know me?") in a massacre of men women and children. Then there is a ressurection of righteous and unrighteous that were lucky enough to die before god killed them. Perfectly loving, just, and sensical!
The fact of the matter is, as Mark Twain put it, the bible is the most damning biography ever written. The God of Love is a bloodthirsty god that killed millions, and supposedly in the future plans on killing billions more. He gave birth to pain, fear, disease, famine, war (as jane goodall showed, primates wage war just as humans do. we're just better at it), and afterwards looked at the carnage and said "it is good". I'm sorry but the god you believe in is a fairy tale. His world and book contradict his very nature.
I don't believe in destroying god, but seeing as how this is an open debate I don't feel to bad about showing the illogical reasoning behind it.
