Before the astonished gaze of Zacharias, at this supreme moment of his priestly service, there appeared, standing on the right of the golden altar of incense, an angel of the Lord. Many generations had passed in Jewry since any visible presence other than mortal had been manifest within the temple, either in the Holy Place or the Holy of Holies; the people regarded personal visitations of heavenly beings as occurrences of the past; they had come almost to believe that there were no longer prophets in Israel. Nevertheless, there was always a feeling of anxiety, akin to that of troubled expectancy, whenever a priest approached the inner sanctuary, which was regarded as the particular abode of Jehovah should He ever again condescend to visit His people. In view of these conditions we read without surprize that this angelic presence troubled Zacharias and caused fear to fall upon him. The words of the heavenly visitant, however, were comforting though of startling import, embodying as they did the unqualified assurance that the man's prayers had been heard, and that his wife should bear him a son, who must be named John.[191] The promise went even further, specifying that the child to be born of Elisabeth would be a blessing to the people; many would rejoice at his birth; he would be great in the sight of the Lord, and must be guarded against wine and strong drink;[192] he would be filled with the Holy Ghost, would be the means of turning many souls to God, and would go before to make ready a people prepared to receive the Messiah. Doubtless Zacharias recognised in the predicted future of the yet unborn child the great forerunner, of whom the prophets had told and the psalmist had sung; but that such a one should be offspring of himself and his aged wife seemed impossible despite the angel's promise. The man doubted, and asked whereby he should know that what his visitant had spoken was true: "And the angel answering said unto him, I am Gabriel, that stand in the presence of God; and am sent to speak unto thee, and to show thee these glad tidings. And, behold, thou shalt be dumb, and not able to speak, until the day that these things shall be performed, because thou believest not my words, which shall be fulfilled in their season."[193] When the highly blessed though sorely smitten priest at length came from within and appeared before the expectant congregation, already made anxious by his delayed return, he could but mutely dismiss the assembly and by signs indicate that he had seen a vision. The penalty for doubt was already operative; Zacharias was dumb.
