What did Jesus do from age 12 to 30?

The short answer

The Gospels tell us only a little. After his visit to the Temple at twelve, Jesus went home to Nazareth, lived with his family, and grew up. By the time he began to teach at about thirty, his neighbors knew him as a carpenter.

What the record says

Luke is the only Gospel that tells about Jesus at twelve. After his parents found him in the Temple, Luke writes:

“And he went down with them, and came to Nazareth. He was subject to them, and his mother kept all these sayings in her heart. And Jesus increased in wisdom and stature, and in favor with God and men.” (Luke 2:51-52)

Then the story jumps ahead. “Jesus himself, when he began to teach, was about thirty years old” (Luke 3:23).

A few clues fill in the gap. The people of Nazareth called him “the carpenter” and named his brothers (Mark 6:3). He went to the synagogue on the Sabbath, “as was his custom” (Luke 4:16). Beyond that, nobody knows the details of those eighteen years. Anyone who tells us exactly what happened is guessing.

Some churches read “brothers and sisters” as cousins, or as Joseph’s children from before.

How Son of Man tells it

Son of Man is a novel. It imagines the years the Gospels skip. In the novel he goes by Yeshua, the name his family would have called him. In chapter five, Containment, Yeshua comes home from the Temple to a village full of talk. His father hands him a plane and puts him back to work in the shop beside him. When his mind drifts back to Jerusalem, Joseph tells him plainly where his life is for now.

“This is your life right now. This room. This work.”
