What you must logically and necessarily do if you believe in the Abrahamic God

If you believe in the Abrahamic God then you would logically and necessarily have to obey His laws after knowing He has taken the trouble to reveal them.

When the Catholic Church was the European hegemon, European laws and monarchs were controlled by the Catholic Church until it lost the Wars of the Reformation. But even under Protestantism, Europeans framed their laws according to what they believed the Bible permitted and commanded.

The purpose of God is also to see that the ruler does not exceed the laws set by God and be a check on his power. "Be you ever so mighty, the law is above you" is a universal idea. Emperors of Ancient China were presumed to be given the Mandate of Heaven until it was withdrawn.

But if you believe in the eternal, omnipotent and supreme Abrahamic God who created the Universe and even now controls it, you would have to believe that everything happens for a reason, even bad things. We are being pushed along with a narrative towards a conclusion and this means our suffering has meaning, but it will only have meaning if we make a point of learning from our mistakes.

If you are an atheist, you don't have to believe in God to accept that the Koran containing the rule of law is considered to be most in harmony with the Seven Noahide laws by the rabbis of God's Chosen People.  The Koran is believed by Muslims to be from God and is clearly more efficacious in promoting the rule of law than the New Testament written by mortal and fallible men such as Matthew, Mark, Luke and John. There are no Christian theocracies now accept the Vatican, but Iran under sharia has allowed it to defy the might of America and its allies.

There is no requirement to believe in God to restore the patriarchy, but it helps.

Christianity

Christianity is a terribly warlike religion. Forget what Christians did to non-Christians in their crusading wars of imperialism. Just look at what they did to each other!

1) The European Wars of Religion which included the Thirty Years War amongst many others

2) The American Civil War when they were all English-speaking, Christian and Protestant too!

3) WW1

4) WW2

It is not surprising that they would feel a little guilty and uneasy about their white privilege AKA imperial privilege which they don't like to talk about, which they no longer even learn about as schoolchildren. Presumably, it is because a largely atheist population will not suffer to learn about the immensely complex doctrinal and political reasons which caused the Wars of the Reformation and the break up of the Holy Roman Empire, which was a kind of Christian Caliphate.

If Europe had been Muslim, there would have been no need for the Wars of the Reformation. If Europe had already been Muslim and following Islamic rules of warfare, there would have been no WW1 let alone its continuation which was WW2, both framed as the Second Thirty Years War.
