I do not consider believers giving their version of gods and their natures to be myth-making.
I do. We see it on these threads regularly. They're vamping, giving ad hoc answers to the challenges skeptic offer. Every believer believes in a different god, and their claims about their gods evolve.
Maybe you've seen this joke from Emo Philips before. Each of these subdivisions (after atheist) represents a new theology and a implies a different god. In the end, one of these guys is killed for worshiping the wrong god. Just a joke, and just fictitious denominations in some cases, but it represents the evolution of religions and their denominations, and with them, their theologies and god descriptions:
I was walking across a bridge one day, and I saw a man standing on the edge, about to jump off. So I ran over and said, "Stop! don't do it!"
"Why shouldn't I?" he said.
I said, "Well, there's so much to live for!"
He said, "Like what?"
I said, "Well...are you religious or atheist?"
He said, "Religious."
I said, "Me too! Are you Christian or Buddhist?"
He said, "Christian."
I said, "Me too! Are you Catholic or Protestant?"
He said, "Protestant."
I said, "Me too! Are you Episcopalian or Baptist?"
He said, "Baptist!"
I said, "Wow! Me too! Are you Baptist Church of God or Baptist Church of the Lord?"
He said, "Baptist church of God!"
I said, "Me too! Are you original Baptist Church of God, or are you reformed Baptist Church of God?"
He said, "Reformed Baptist church of God!"
I said, "Me too! Are you Reformed Baptist Church of God, reformation of 1879, or Reformed Baptist Church of God, reformation of 1915?"
He said, "Reformed Baptist Church of God, reformation of 1915!"
I said, "Die, heretic scum", and pushed him off.
I do not consider branching theologies to be myth-making.
How is that not mythmaking, and what would mythmaking look like instead in your estimation?
Dictionary definitions are not useful for determining what omnipotent means as it applies to God.
But they are useful in determining how people use words and in turn, what they think. I doubt that people go to dictionaries to decide how their gods are, but lexicographers go to people and their expressed thoughts to decide how to define words in their dictionaries.
I believe that God is as described in the Bible and other Abrahahamic scriptures. "there is nothing outside of His ability to accomplish" means God can DO anything, it does not mean that God can BE what God is not. For example, God cannot become less that omnipotent, less than omniscient, and God cannot become a man, since God would then no longer be God.
OK, and others believe other things. That's what I mean. Perhaps you aren't aware of the degree to which you contribute to your theology and your view of the deity. You've expressed several ideas that were original to you as best I can tell. The god you describe is different from the usual description of the god of Abraham. The god you describe doesn't seem likeable even to you, and you don't seem to think that it has any duty to you or anybody else. Apologies if I got that wrong or that sounds blasphemous to you.
