Luke 2:47. “All that heard him were astonished at his understanding and answers”
The Prophet Joseph Smith taught the following about Jesus Christ’s youth:
“When still a boy He had all the intelligence necessary to enable Him to rule and govern the kingdom of the Jews, and could reason with the wisest and most profound doctors of law and divinity, and make their theories and practice to appear like folly compared with the wisdom He possessed; but He was a boy only, and lacked physical strength even to defend His own person; and was subject to cold, to hunger and to death” (History of the Church, 6:608).
