Children of .... India?

Been wondering lately - what if God had chosen another nation as His Children, instead of Israel? What would our Christian belief system look like if He had chosen the Egyptians, or the Chinese, or the Indians, or Native Americans, or one of the African nations? What would His Word look like? What major changes to our beliefs as Christians would there be if it were all rooted in a different culture, other than the Jewish nation?

One can only imagine!
