In RC Sprouls book, The Glory of Christ, he takes 15 events from Jesus life where its as if the glory of the deity of God particularly breaks through the perfect humanity of Christ. He writes, His humanity served as a veil that concealed the splendor of His deity. Yet there were moments when His glory shone through. It was as if the vessel of His human nature was not strong enough to conceal it at all times (p9).

In Luke 2 we read, “After three days they found him in the temple, sitting among the teachers, listening to them and asking them questions. And all who heard him were amazed at his understanding and his answers.”

It is not necessary to appeal to the divine in Jesus to account for His ability to astonish the learned professors. He could have done it with the sheer strength of His unaided perfect humanity

What a fallen man can learn by age forty could easily be surpassed by what an un-fallen person could learn by age twelve. A perfect twelve-year-old would be perfect in the clarity of his thought. His thinking would not be marred by errors of reasoning. The mind of the twelve-year-old Jesus would have been enough to astonish the most learned of fallen men

In Jesus reply to his parents when they finally find him in the temple after three days of missing him, he shows them two things: 1. that He is their son but also their savior, and 2. He came to do Gods will. We conclude then that this narrative of Jesus amazing the teachers in the temple reveals the glory of His identity [the
savior of the world], of His mission [to obey the Father’s will], and most clearly, of His perfect human nature (p49, 50, 52).
