I'm not sure. The Old Test God got pissed and punished the people during their lifetimes. The New Test God has a kid, kills his kid and then creates an eternal torment.
I'd say he changed... he came up with more a deviant way of trying to get people to love him. If we go by fundamentalist doctrines (some of which aren't found in the Bible unless you cherry pick verses to make it fit) If we go by what some others say... God was an angry god in the Old Test, then had a kid and calmed down, now he loves everyone. Either way, change took place.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
