These questions are on topic.how could Jesus learn if He was already omniscient? How could Jesus grow in wisdom?
Which of the 3 options, from the OP, best express how this could be?
Here they are again:
- Jesus continued to exercise some dimensions of omniscience while on earth and the full exercise of his omniscience was subject to God the Father’s parameters;
- Jesus never failed to function on the level of the moral attributes, but frequently does not display the amoral attributes such as omniscience as these seemed to be subject to the guidance of the Holy Spirit and come to the human conscious level at the Spirit’s choosing (Dan Wallace’s view).
- In his incarnation, Jesus laid aside the use of his attribute of omniscience.
