Luke 2:50

And they understood not the saying which He spake unto them.

The three days' search with its attendant anxiety may well have aroused the thought in Mary's heart that the prophecy of Simeon was even now being fulfilled. But at last Mary and Joseph found Jesus, after assiduously searching over the whole city, in the Temple, sitting in the midst of the learned teachers, in the hall where the school-classes of the children of the Law, the great high school, assembled for advanced instruction to learn to keep the commandments. There He was sitting, outwardly in the role of a pupil, but in reality in earnest conference, in which He assumed almost a teacher's functions. He was giving due attention to the explanations of the doctors, but He was also putting searching questions, to the amazement of all those that were present to hear Him. His understanding, His ability to penetrate a given matter, and the answers which He gave, were of a kind to provoke astonishment. Here was something of the rare insight and the ease of presentation which in later years delighted His audiences. But Mary and Joseph were disturbed on account of the apparent audacity of the boy, which seemed to them like forwardness. And Mary, still full of the excitement of the search and with her mother's heart yearning toward her Son, reproachfully asked why He had dealt with them thus, not realizing that the fault was not His, but theirs. Note: The tactful way in which Mary refers to Joseph is an indisputable proof of the wisdom with which she brought up her Child; a lesson for many modern parents. They had sought Him with anxious solicitude. But Jesus does not accept the reproof. Not reproachfully, but with all the sincerity and boldness of holy childhood, He asks her why they had sought in that manner. He gives them an inkling of the purpose of His life. They should know that He must be about His Father's business. This is the obligation of His life: the things of His Father He must be engaged in, be concerned about. The Temple was the place where the service of His Father was supposed to be most perfect, where the Word of grace was supposed to be taught. "Wherefore the Temple was also called His sanctuary and sacred dwelling, since there He, through His Word, showed His presence and permitted Himself to be heard. Thus Christ is about His Father's business when He speaks to us through His Word and through it brings us to the Father. " This answer of Jesus, with its implication of divine sonship, was beyond the understanding even of Mary, who had remembered all the sayings concerning her Son.
