What I always find strange is, out of all the religions to have arisen on the Earth, it’s the beliefs of a bunch of wandering bronze-age goatherds that comes to dominate the world. Three different sets of the same belief, in fact, since Christianity and Islam are both off-shoots of Judaism.
That He hasn’t come down centuries ago to tell His kids to stop squabbling is an insight into His character. Who is this God? Well, he’s a volcano god, originally. The Hebrews followed a pillar of fire by night and a column of smoke by day, and came to a burning mountain. Along the way, an earthquake parted the Red Sea. Volcano God; QED.
And somehow this volcano god has elevated Himself to being the ruler of the entire universe. As the events of the OT range farther away from mountains and volcanoes, it’s become necessary for Yahweh to extend his reach too, so that he’s no longer just the god of the mountain, but all He surveys. He’s had to get successively and exponentially taller.
This is the “God of the Gaps” fallacy at work; by the time we realised that, actually, there isn’t an angry demon living in the mountain breathing smoke and fire, Yahweh had already emigrated to living in the sky. When we learned to fly, He moved up into “the heavens”; when we got into orbit, He took up residence outside physical reality. As our knowledge grows, the places God could be hiding become more abstract, so that believers are able to cling to the idea that He’s still there somewhere.
And this is just one specific God; Yahweh. When humans explored the summit of Mount Olympus and found that Zeus just wasn’t there, they stopped believing in him. But when we climbed Mount Sinai, we assumed Yahweh had flown away.
