When Jesus reached the age of twelve years, He entered—according to Jewish custom—upon a new and important period in His life. You may be used to thinking of Jesus as a very wonderful boy, altogether different from other boys. That is not quite true. Jesus was a perfectly natural and normal boy. He liked to run and jump and play the games that other boys played. He had to go to school as other Jewish boys did—first at His mother's knee, then at the village synagogue. Jesus was unlike other boys in that He began early to understand something of the nature of His mission upon the earth. This made Him like serious things, and often to think about the teachings of God; for it was the aim of all Jewish education to learn about God and His commands, and how to keep them. Now, when Jesus became twelve years of age, there came to Him many new duties. The Jewish law required that He should assume all the religious responsibilities that devolved naturally upon a faithful Jew. Amongst other things, Jesus must hereafter go to the temple three times a year, to fulfill the demands of the law. Accordingly, when Joseph and Mary set out for Jerusalem, to observe the Feast of the Passover, soon after their eldest son's twelfth birthday, they took Him with them.

It is needless here to follow in detail the journey of the pilgrims over the great highway, across the Plain of Jezreel to Bethshean, down the western side of the Jordan Valley to Jericho, and then four thousand feet upward over the barren, robber-infested hills of the wilderness of Judea to Jerusalem. Jesus seems to have been much impressed by the road, for He referred to it later in the parable of the Good Samaritan.
When the celebration of the feast of the Passover was accomplished, Joseph and Mary set out to return to Nazareth. They had complete confidence in Jesus, so they did not look for Him till they reached Bethany. Jesus was not there to be found. Anxious at heart the parents returned to Jerusalem; and there, after three days, they found Him discoursing in the temple with Shammai and the learned teachers of the temple. The boy's zeal for knowledge had caused Him to remain at the temple even after the feast was over. "And all that heard Him were astonished at His understanding and answers."
When Mary saw her son in the midst of the learned men of Israel, she cried to Him, "Son, why hast thou thus dealt with us? Behold, thy father and I have sought thee sorrowing."
"And He said unto them. How is it that ye sought me? Wist ye not that I must be about my Father's business?"
"And they understood not the saying which He spake unto them."
His Father's Business.
It was, indeed, a strange saying to understand. Not Joseph and Mary alone, but countless thousands of people have failed to understand it. Do you think you know what the boy Jesus meant? Of course, to understand, one must know what the Father's business is. Then we can understand what Jesus thought about His mission on the earth. "For," Jesus said many years later when He had grown to manhood, "I came down from heaven, not to do mine own will, but the will of Him that sent me."
What, then, is the will of God? What is His Father's business? Once, many hundreds of years before Jesus was born, God gave to a man named Moses a marvelous revelation. Moses saw how the earth had been formed, and how living things were put upon it. He saw how man was shaped in the image of God and placed upon the earth to have dominion over it. Then God said to Moses, "Behold, this is my work and my glory—to bring to pass the immortality and eternal life of man."
