What did Jesus know as a child?
Question 3009
The Gospels give us only glimpses into Jesus’ childhood, yet those glimpses raise fascinating questions. How did the incarnation work in practice during those early years? Did the baby Jesus know He was God while lying in the manger? Did the toddler Jesus understand the Trinity? What was going on in His mind as He grew up in Nazareth? While Scripture does not answer every question, it gives us enough to understand the essential truths about Jesus’ developing human knowledge.
What Scripture Tells Us
Luke provides the clearest window into Jesus’ childhood. He tells us that “the child grew and became strong, filled with wisdom. And the favour of God was upon him” (Luke 2:40). And again, “Jesus increased in wisdom and in stature and in favour with God and man” (Luke 2:52). The word “increased” (προέκοπτεν, proekopten) means to advance, to make progress, to move forward. This was genuine development, not merely an appearance of growth while secretly possessing all knowledge.
This tells us that in His human nature, Jesus experienced real intellectual development. He learned to walk and talk. He learned the Scriptures. He learned Joseph’s trade as a carpenter. He grew in understanding as any child does, though without sin and with the special blessing of God upon Him.
The one story we have from Jesus’ childhood confirms this. At age twelve, Jesus stayed behind in Jerusalem at 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” (Luke 2:46-47). Notice that He was both asking questions and giving answers. He was learning and teaching. The teachers were astonished at His understanding, suggesting it was beyond His years but also that He was genuinely engaging in the learning process.
Two Natures, One Person
To understand Jesus’ knowledge as a child, we must hold together the two natures united in His one Person. In His divine nature, Jesus possesses all the attributes of God, including omniscience. “In him are hidden all the treasures of wisdom and knowledge” (Colossians 2:3). As God, Jesus knows everything—past, present, and future; all actual and possible things.
But in His human nature, Jesus had a genuine human mind that developed according to normal human processes. This is part of what it meant for Him to “empty himself” and take “the form of a servant” (Philippians 2:7). He did not draw upon His divine knowledge to shortcut the human experience. He genuinely learned, genuinely grew, and genuinely developed as a human being.
How these two work together in one Person is a mystery we cannot fully comprehend. The eternal Son of God, who knows all things, united Himself with a human nature that did not know all things. Both statements are true simultaneously. It is not that Jesus’ divine nature was limited but that His human nature operated according to its own capacities, which developed over time.
What the Child Jesus Likely Knew
While Scripture does not give us detailed information, we can make some reasonable inferences. The child Jesus would have learned the Old Testament Scriptures thoroughly. Jewish boys began formal Scripture education at age five or six. By twelve, Jesus’ knowledge astonished the temple teachers. By His adult ministry, He quoted Scripture with perfect ease and authority.
Mary and Joseph would have taught Jesus about His miraculous birth. Luke tells us that “Mary treasured up all these things, pondering them in her heart” (Luke 2:19, 51). It is reasonable to assume she shared at least some of these things with Jesus as He grew. The angelic announcements, the visit of the shepherds and wise men, the prophecies of Simeon and Anna—these would have been part of family memory.
Jesus would have learned the trade of carpentry from Joseph. Mark 6:3 calls Him “the carpenter,” indicating He actually practised the trade. He learned the skills, developed the muscles, calloused His hands. This was real work, really learned.
Throughout His growth, Jesus remained sinless. Even as a child, He did not sin. This does not mean He never made a mistake while learning (knocking something over, misspelling a word), but He never sinned morally. His human will was always perfectly aligned with the Father’s will, even as His human knowledge developed.
The Mystery of the Incarnation
We must be honest about the limits of our understanding here. How exactly the divine and human consciousnesses related in the child Jesus is not explained in Scripture. Some theologians speak of the “voluntary non-use” of divine attributes, suggesting that Jesus in His human nature chose not to access His divine knowledge. Others speak of “accommodation,” where the divine nature accommodated itself to the human experience. These are attempts to explain what Scripture ultimately presents as a mystery.
What we can say with confidence is that the incarnation was genuine. The Son of God really became a human child. He really went through the process of growing up. He really increased in wisdom. This was not a pretence or an illusion but the authentic experience of God becoming man.
Why This Matters
The reality of Jesus’ childhood development matters for several reasons. It confirms the genuineness of the incarnation. Jesus did not skip the messy, vulnerable stages of human life. He was a real baby, a real toddler, a real child. He experienced everything we experience in growing up, apart from sin.
It also provides comfort and example. Every stage of human life has been lived by Jesus. Children can know that Jesus understands what it is to be a child. Parents can know that Jesus experienced childhood. The challenges of learning, of growing, of developing are not foreign to our Lord.
Furthermore, it demonstrates Jesus’ full identification with humanity. He did not appear on earth as a fully formed adult. He submitted Himself to the entire human journey, from conception to adulthood, sanctifying every stage by His presence and perfect obedience.
Conclusion
As a child, Jesus had genuine human knowledge that developed over time. He increased in wisdom and stature. He learned Scripture, learned a trade, and learned about His own miraculous origins from His parents. At the same time, He remained the eternal Son of God whose divine nature possesses all knowledge. How these two work together is part of the unfathomable mystery of the incarnation. What we know for certain is that Jesus’ childhood was real, His growth was genuine, and through it all, He remained the holy Son of God preparing for the mission that would save the world.
