Every year Yeshua’s [Jesus’] parents went to Yerushalayim [Jerusalem] for the festival of Pesach [Passover]. When he was twelve years old, they went up for the festival, as custom required. But after the festival was over, when his parents returned, Yeshua remained in Yerushalayim.
They didn’t realize this; supposing that he was somewhere in the caravan, they spent a whole day on the road before they began searching for him among their relatives and friends. Failing to find him, they returned to Yerushalayim to look for him.
“On the third day they found him — he was sitting in the Temple court among the rabbis, not only listening to them but questioning what they said; and everyone who heard him was astonished at his insight and his responses.
When his parents saw him, they were shocked; and his mother said to him, “Son! Why have you done this to us? Your father and I have been terribly worried looking for you!”
He said to them, “Why did you have to look for me? Didn’t you know that I had to be concerning myself with my Father’s affairs?” But they didn’t understand what he meant.
“So he went with them to Natzeret [Nazareth] and was obedient to them.” (Luke 2:41-51, The Complete Jewish Bible)
It might seem that Jesus’ reply to his mother was disrespectful and “teenagerish.” But Scripture reiterates that Jesus was “without sin,” so we can be sure that he was merely amazed that his earthly parents didn’t “get it” — why he felt the need to spend time in the temple (his Father’s house) learning from others who had studied the Scriptures.
I wonder if Jesus, when he was a teenager — the Son of God in human form — had any memory of the times throughout history when he had appeared in pre-incarnate form to people like Adam and Eve (Genesis 4:8-9) and their descendants, Abraham (Genesis 18:1), his son Isaac (Genesis 26:2), and Jacob /a.k.a. Israel (Genesis 28:12-15; 32:24-30). This supernatural body was described by Luke and John after Jesus’ resurrection (Luke 24:13-43; John 20:10 – 21:14).
Have you not heard?
The Lord is the everlasting God,
the Creator of the ends of the earth.
He will not grow tired or weary,
and his understanding no one can fathom.
He gives strength to the weary
and increases the power of the weak.
Even youths grow tired and weary,
and young men stumble and fall;
but those who hope in the Lord
will renew their strength.
They will soar on wings like eagles;
they will run and not grow weary,
they will walk and not be faint.”
