But had it not been for this sorrow they might never have been qualified to receive the first tidings of the near approach of the Messiah. _Sorrow_ opens our eyes, and bids us see visions within the vail, which cannot be described by those who have not wept. _Sorrow_ leads us up the steep mountain of vision, and opens the panorama which lies beyond the view of those who dare not attempt the craggy steep. _Sorrow_ prepares us to see angels standing beside the altar of incense at the hour of prayer, and to hear words that mortal lips may not utter until they are fulfilled. _Sorrow_ leads us to open our house to those who carry a great anguish in their hearts, who come to us needing shelter and comfort; to discover finally that we have entertained an angel unawares, and that in some trembling maiden, threatened by divorce from her espoused, we have welcomed the mother of the Lord (ver. 43). Shrink not from sorrow. It endures but for the brief eastern night; joy cometh in the morning, to remain. It may be caused by long waiting and apparently fruitless prayer. Beneath its pressure heart and flesh may faint. All natural hope may have become dead, and the soul be plunged in hopeless despair. "Yet the Lord will command his loving-kindness in the morning;" and it will be seen that the dull autumn sowings of tears and loneliness and pain were the necessary preliminary for that heavenly messenger who, standing "on the right side of the altar of incense," shall assure us that our prayer is heard. III. THE ANGEL'S ANNOUNCEMENT.--One memorable autumn, when the land was full of the grape-harvest, Zacharias left his home, in the cradle of the hills, some three thousand feet above the Mediterranean, for his priestly service. Reaching the temple he would lodge in the cloisters, and spend his days in the innermost court, which none might enter save priests in their sacred garments. Among the various priestly duties, none was held in such high esteem as the offering of incense, which was presented morning and evening, on a special golden altar, in the Holy Place at the time of prayer. "The whole multitude of the people were praying without at the time of incense." So honourable was this office that it was fixed by lot, and none was allowed to perform it twice. Only once in a priest's life was he permitted to sprinkle the incense on the burning coals, which an assistant had already brought from the altar of burnt-sacrifice, and spread on the altar of incense before the vail.
