Let’s suppose there are such things as angels or devils, and that, in our understanding of “time,” they predate our own creation. Does that mean God has always had company?
By any reckoning that our understanding of God can support, angels and devils are created beings, so they clearly will not answer.
Then press the question in any way we can, substitute anything at all – anything at all – for “angels” and “devils”, yet still we arrive at God, alone.
And as God has said, “It is not good to be alone.”
