But what is he responsible for?
When the Catholic Nazi Germany attempts a genocide, a man is blamed.
When Hebrews commit genocide on the Canaan, it is his will.
We have plagues, on Catholic countries, for example. The Dark Ages were committed in Yahweh's name. Were they?
Why would Yahweh plunge the civilization of Rome, with health, farming and sanitation, back into the primitive squalor of ancient Jerusalem, if so?
If not, why did he not stop such a terror? It seems to be in His purview.
How does one determine if an act is done in God's will, or men's will?
Does the Bible tell us?
Understanding that free will is a constraint - we can also understand that mob's and large numbers of people lose free will, does this fall into God's purview, then?
In short, how does one know what God is responsible for;
Any group decision?
A decision influenced by prayer?
The position is that presented by Romans 13:
The position of the OP is: those atrocities committed by governments, God's will, and he is responsible for them.Obey the rulers who have authority over you. Only God can give authority to anyone, and he puts these rulers in their places of power. 2 People who oppose the authorities are opposing what God has done, and they will be punished. 3 Rulers are a threat to evil people, not to good people. There is no need to be afraid of the authorities. Just do right, and they will praise you for it. 4 After all, they are God’s servants, and it is their duty to help you.
