I'd like to see EVIDENCE of THIS source!
Amos 3
7 Surely the Lord God will do nothing, but he revealeth his secret unto his servants the prophets.
Which prophet revealed what God decided your canon would be?
He says “will do nothing”.... nothing. Not “somethings” or “a little here and there.” He says God will do nothing. That’s definitive. Explicit.
So again, who was the prophet that revealed God’s will on which books were to be included in your canon and which were excluded?
