We can easily understand, even if we may not apologize for, the incredulity of Zacharias. There are crises in our life when, under profound emotion, Reason herself seems bewildered, and Faith loses her steadiness of vision. The storm of feeling throws the reflective powers into confusion, and thought becomes blurred and indistinct, and speech incoherent and wild. And such a crisis was it now, but intensified to the mind of Zacharias by all these additions of the supernatural. The vision, with its accessories of place and time, the message, so startling, even though so welcome, must necessarily produce a strange pertubation of soul; and what surprise need there be that when the priest does speak it is in the lisping accents of unbelief? Could it well have been otherwise? Peter "wist not that it was true which was done by the angel, but thought he saw a vision;" and though Zacharias has none of these doubts of unreality--it is to him no dream of the moment's ecstasy--still he is not yet aware of the rank and dignity of his angel-visitant, while he is perplexed at the message, which so directly contravenes both reason and experience. He does not doubt the Divine power, let it be observed, but he does seek for a sign that the angel speaks with Divine authority. "Whereby shall I know this?" he asks, reminding us by his question of Jacob's "Tell me thy name." The angel replies, in substance, "You ask whereby you may know this; that is, you wish to know by whose authority I declare this message to you. Well, I am Gabriel, that stand in the presence of God; and I was sent to speak unto you, and to bring you these good tidings. And since you ask for a sign, an endorsement of my message, you shall have one. I put the seal of silence upon your lips, and you shall not be able to speak until the day when these things shall come to pass, because you believed not my words." Then the vision ends; Gabriel returns to the songs and anthems of the skies, leaving Zacharias to carry, in awful stillness of soul, this new "secret of the Lord."
