"Your definition of God as a deity."
God is a deity, though, at least as understood in Christianity. Oxford Dictionary of English defines "Deity" as "A god or goddess".
People of deeply felt faith don't go by dictionary definitions.
Very often, you'll find they discard stuff written in books and listen to their hearts. The perception of God as some man up in the sky is a childish interpretation of something far too grandiose for the human mind to come near to grasping.
If you want to see God as that, and discard that concept you are welcome to -- so do I (discard that concept).
But if you were to follow that sense of complete awe and overpowering majesty when you look up at the night sky, or contemplate the miracle of a growing foetus in a female body, and wonder if there isn't some unifying power and unsolveable mystery behind it all to great for our tiny little minds to come close to understanding -- then we must go beyond the man in the sky strawman.
It's that sense of complete wonder that has always humans wordlessly simply wonder in great awe, and to feel that awesome wonder -- be they the most primitive caveman worshipping the sun, or a scientist knowing that he hasn't even touched on that mystery, and knowing that IF there is a unifying power behind it all, then that power also created the rules of science. And feels humble beside it.
I know many humble, brilliant, Godfearing scientists who nevertheless don't think of God as a man in the sky as defined by a dictionary.
And usually that faith is most private and even secret. There is no demand that others share it, such as in TRA ideology.
But most do have an objection to being put into a cliched box, such as "you worship a deity in the sky, yes you do." And being told you MUST worship a deity in the sky, because that's how how the dictionary defines God. Yes, a complete straw man.
Well, sorry if I said too much. But this insistence that we all worship some distant and logic-defying deity in heaven is very annoying.
