I think it's important to distinguish between the Law delivered to Moses and Israel and the history of the nation. There were many times in the history of lsrael when actions were taken that did not please God. Even Moses made mistakes, and, ultimately, he was prevented from entering the Promised Land.
That's one the one hand. On the other hand, there's the conduct which the Tanakh attributes unambiguously to Yahweh.
On those occasions when God did tell lsrael to conquer a people, was this not justice being metered out against those who practised child sacrifice, divination and idolatry? Who are we to claim that this was not justice?
Well ...
Exodus 22:29-30 You must give me the firstborn of your sons. Do the same with your cattle and your sheep. Let them stay with their mothers for seven days, but give them to me on the eighth day.
Joshua 6:21 They devoted the city to the LORD and destroyed with the sword every living thing in it - men and women, young and old
Numbers 31:25 (God claims a 'tribute' of 32 captives.)
Judges 1: 30-39 (the sacrifice to Yahweh of Jephthah's daughter.
And of course the New Testament.
I don't think Yahweh's record with human and child sacrifice will stand the close-up look. Nor is it easy for modern humans to recapture the notion that sacrifice of lives to God in cold blood is appropriate from time to time.
The development of thinking in Greek culture may have coincided with the appearance of Christ, but this would have been all a part of God's timing.
No, Greeks had been developing philosophy since at least the time of Thales, 7th-6th century BCE, and the ideas I spoke of were around from the time of Plato (5th century BCE) onwards.
As well as that, the "golden rule" has been found in cultures long before Yahweh comes on the scene c. 1500 BCE, almost certainly because humans have an evolved morality as well as an acquired one, and the evolved part includes like of fairness and reciprocity, hence is found all over the world.
For Christ to appear, the conditions of his coming must have been foreseen, making it possible for the Gospel to be preached throughout the Roman Empire, and the world.
If that were so, would it not have been vastly more efficient to have Jesus born in Rome, and counterparts of Jesus in all of the other cultures of the world at the same time? As it stands, the native peoples of many countries around the world had never heard of Jesus till the 19th and 20th centuries.
To me the Bible and Holy Spirit provide us with the best evidence of God's existence. .
If that helps you to deal with other people with decency, respect and inclusion, you'll get no argument from me.
I have not come across a satisfactory answer from any secular humanist or atheist to counter the prophecy of scripture and history of Israel. Certainly the Jews would not have survived, or returned after two thousand years of dispersal, had God not been running the show.
I always find this claim peculiar. Frequently murderous Christian antisemitism was Jesus' gift to the Jews, all the way through to the holocaust. Zionism from the 19th century on was driven by a set of cultural attitudes amongst Jewish people reinforced by antisemitism, and in the 20th century also by slogans and politics.
The Jewish takeover of Palestine was also a very bad day for the Palestinians, and this continues to be the case. If returning Jewish people to Palestine is God's idea of justice then God has a very strange idea of justice. I'm not antisemitic ─ my children have some Jewish ancestry ─ but there are times when I'm heartily opposed to the politics of Israel.
Which brings me back to what I said about decency, respect and inclusion.
