The israelite were commanded to remove 7 people groups from the land. These were the baby burning cults. God gave them 400 years to repent.
They didn't. The 7 groups are prophetic. The 7 years are a type of revelation.
For instance, the canaanites were submitters. One 5th of the planet today are submitters. There is a multifront war with them.
These guys have a prophetic judgement against them. It will go down just like canaan. Should the baby burning cult have been allowed to spread and cover the world?
Would you rather be debating a baby burner trying to justify why your baby has to burn for his god statue?
Basically, in antiquity, the view was that you were supposed to "destroy" foreigners, anyone who was different, who worshipped differently, had land or other forms of wealth you wanted, etc. That being the case, ancient people came up with justifications, which were often written down. Some of these justifications were religious. The Jews were no different.
We have their ancient justifications, partly because these were preserved in scripture that became foundational writings for Christianity, but as I said, ALL ancient peoples found ways -- often religious ways -- to justify war, destruction, enslavement, and what-have-you. The past was a violent place. People were not pleasant to one another, and their religions were often quite unpleasant and violent, too.
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.
