The New Testament tells very little about the boyhood and early manhood of our Saviour. One incident, however, is narrated. Luke 2:41-50. Joseph and Mary, we are told, were in the habit of going up from Galilee to Jerusalem every year in the spring at the feast of the passover. When Jesus was twelve years old, he went up with them. But when they left Jerusalem on the return, Jesus remained behind in the Temple, to study the Old Testament; and when Joseph and Mary found him, he replied to their inquiries, "Knew ye not that I must be about my Father's business?" The incident shows the presence even in the human consciousness of the boy Jesus of a knowledge of the great mission that he was called to fulfill and of his special relation to God. Luke 2:51, 52 But the consciousness of these great things did not prevent our Saviour from performing the humble tasks of daily life and from being obedient to his human parents. Luke 2:51, 52. Jesus became a carpenter, and since Joseph also was a carpenter, no doubt Jesus learned the trade in early youth. Mark 6:3; Matt. 13:55. For many years, till he was about thirty years old, the Saviour of the world labored at the carpenter's bench, and lived as an obedient son in a humble home at Nazareth. Luke 3:23. At last, however, the time came for the beginning of his public ministry. Before that ministry is studied, it may be well to cast a glance at the condition of the country into which Jesus now came forward. When Herod the Great died in 4 B.C., his dominions were divided among his three sons. Archelaus received Judea, the southern part of Palestine, with Jerusalem as its chief city; Herod Antipas, the "Herod" who is mentioned in the Gospels in connection with Jesus' public ministry, received Galilee and a district to the east of the Jordan River called Perea; and Philip received a region lying to the east of Galilee and to the north of Perea. When Archelaus was banished in A.D. 6, his territory was placed under the control of Roman officials called procurators. The procurator who was in office during Jesus' public ministry was Pontius Pilate. Herod Antipas, with the title of "tetrarch," continued to rule until A.D. 39; Philip until about A.D. 33. The public ministry of Jesus extended from A.D. 26 or 27 to A.D. 29 or 30. During most of that time he was in the territory of Herod Antipas and of Pontius Pilate, though occasionally he entered the territory of Philip. Matthew 3:1-12, and Parallels The beginning of Jesus' public ministry was prepared for by the work of John the Baptist. Matt. 3:1-12, and parallels. John was the last and greatest prophet of the old dispensation, who came just before the dawn of the new age. For centuries prophecy had been silent. But at last a prophet came in the spirit and power of Elijah to prepare the heart of the people for the promised Messiah.
