Truly, God is not a hypothesis. He lives. His name is I AM. And I've known Him personally for half a century and counting.
Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. John 8:58
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. Romans 8:9
Man is NOT the measure of God.
Job and his friends tried to be the measure of God - they were speaking words without knowledge - and God responded in chapters 38-41. Job's reaction:
Hear, I beseech thee, and I will speak: I will demand of thee, and declare thou unto me. I have heard of thee by the hearing of the ear: but now mine eye seeth thee.
Wherefore I abhor [myself], and repent in dust and ashes. - Job 42:1-6
Now thats on the cusp of wisdom.. for all men and Angels..
Human arrogance even hubris is rebellion and a mask costumed with attitude..
What do you know for sure?.. is usually answered by denial and "fits"..
