So meaning is only derived from other meaningful things?
I don't think you're wrong, but I do think that wrapped within this surface web of interwoven meaning lies a core that cannot be reached by moving from one node to the next in the mesh of words, and that this core may not be meaningful in that sense but powerful ... and able to stir plenty of waves on the surface.
God is a word. I think we can at least agree on that. The word God means something. I think we can agree on that. What the word God means is purely subjective so it is up to each of us to decide the best possible meaning for the word God.
I am currently resonating with a type of meaning for God described on this Wiki page:
https://en.wikipedia.org/wiki/Apophatic_theology
The only reason I reference the page is because I know people are obsessed with who is saying something more than what is being said. This idea is not my creation but a way of interpreting the Holy Trinity. I like the way God is defined in this video.
I like the way he describes how things return back to God like an electrical circuit.
