That "God" is what we think God is.
Few people seem to be able to understand or accept that their idea of what God is, is just their idea of what God is. Instead, they simply presume that God is exactly as they have come to think of God: no doubt, and no mystery.
Misconception about God?
That he exists. Simple. Obvious. Done.
"He Is There and He Is Not Silent" by Francis A. Schaeffer
Ever read it?
I recommend it.
Better yet, read his "Trilogy", which includes that particular book along with "The God Who Is There" and "Escape From Reason".
Yes, I know my Schaeffer. Hence my comment.
That he's there.
Or, if he is, that he cares.
