"even if anyone knows what 'God' means? "

I have the same issue: just what does the word "God" mean? Can "God" even be understood in human terms? And just what is "God"? Not some old, bearded man sitting on a thrown- which seems to be a common misconception- to be "God" is not to be "man" in any shape or form since those words denote physicality. And though I do pray to "God" daily, I'm fully aware that I don't truly know what "God" is. That doesn't mean I don't believe "God" exists- I do.

But having just a human mind, I accept that I'll never, in this life, at least, truly grasp what God is, only that it (I don't use pronouns that refer to humans to describe what is decidedly not human, so "it" is the only choice left) exists.
