It does; however let us also consider that the fledgling Jesus was able to lecture in the Temple; a thing that the vast majority of grown men were unable to do. And what is Christ's spirit as separate from His Godhood; how do you explain that? I think more of Christ's Incarnation for our benefit than for His. God reaching down to us with His Hand from the infinite heights is for our benefit. I'm not sure about the applicability of Jesus growing from from grace to grace merely or mostly so He could experience the agony in the Garden more fully.
