At age 12, in the Temple, Jesus rhetorically asked His human parents, “Did you now know that I must be in my Father’s house?” or “... doing my Father’s business?” (same Greek root, “oikos.”)
Up to that point, the Bible says nothing regarding His self-understanding, so anything we might believe is largely speculative.
Well, I'd say entirely speculative. A question that interests me is to what extent we will learn about those things on which the Bible is silent--or will we even care then?
