Luk 2:42 And when he was twelve years old, they went up to Jerusalem after the custom of the feast.
Luk 2:43 And when they had fulfilled the days, as they returned, the child Jesus tarried behind in Jerusalem; and Joseph and his mother knew not of it.
Luk 2:44 But they, supposing him to have been in the company, went a day's journey; and they sought him among their kinsfolk and acquaintance.
Luk 2:45 And when they found him not, they turned back again to Jerusalem, seeking him.
Luk 2:46 And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions.
Luk 2:47 And all that heard him were astonished at his understanding and answers.
Luk 2:48 And when they saw him, they were amazed: and his mother said unto him, Son, why hast thou thus dealt with us? behold, thy father and I have sought thee sorrowing.
Luk 2:49 And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business?
Luk 2:50 And they understood not the saying which he spake unto them.
At the age of twelve a Jewish boy was to begin to learn his father's business. Joseph was a carpenter but Jesus' Father was God Almighty. He astonished the learned doctors of the written word of God with his understanding and answers. As I think of the titles of Jesus, the Living Word comes to mind. Jesus as a babe growing up as a young Jewish boy was beginning to take hold of who he was and his ministry on earth as a human and as the only begotten Son of God. He is an example to us. When we as humans began to see the things of God and were born again of the Spirit we began to learn and develope in the ministries God has for us. It is a great wonder that God humbled himself in the form of a human infant who grew slowly as a human but with the title and responsibilities of the Son of God. Jesus the Son from heaven was from everlasting. Jesus born of woman was the second Adam, come to redeem his people.
I will try to be clever and say that Jesus is still astonishing the doctors, the doctors of medical science. Jesus heals those with no hope of recovery and the doctors are astonished and they do not understand his miracles. To God be the glory and praise the name of Jesus, our savior for all things are possible with God.
