Welcome, you with the unusual name. I'm not quite sure, should I call you "dood"?
Welcome to the discussion board. It has been a great help to so many seeking to keep some sanity while pursuing freedom from the WTS brand of religious confinement.
You ask some really deep questions. Some who read your note will say there is no God, it doesn't matter. Like you, I have retained belief in God, although altered from what I thought before.
So going on the argument that God exists and the Bible's descriptions of the events are accurate, why all this death and destruction?
As far as the "all ending war" mentioned in Revelation, my thought is that Revelation is a very symbolic book. When it mentions "blood up as high as horse's bridles", etc., surely this is symbolism. To be sure, evil must end somehow. I cannot believe, however, that 99.9% of the world's population is evil and must be destroyed. There is, however a small percentage, probably including the world's leaders and their armies. Anyhow, how evil will be dealt with, I won't even guess how that literally will occur, or when. Just best to leave that in God's hands.
As far as how God fought for the nation of ancient Israel in the past, I think the main point was the protection of the promised "seed", Jesus and his ancestors. The nations would regularly go forth and war against each other (I think this time of year was popular for that), and push and pull to gain territorial advantage. If the nation of Israel was allowed to be wiped out, that would have served Satan's purpose to destroy the possibility of the 'seed' occurring in the nation of Abraham's grandson, that is, Israel.
As far as innocent lives that were lost in the process, I cannot think of a real good explanation.
I don't think God intended to NEVER interfere in earth's affairs, just when his purpose was threatened, he had to correct the course of history, so to speak. So that's why certain wicked and hurtful things go on and on without it seeming like God wants to help, when at other times it seems he surprises people and jumps in and raises kings up or puts them down.
Just a few general thoughts. Welcome to the board, can't wait to hear your story on the "Make New Friends" board.
