Why was Zechariah punished for doubting Gabriel's message, but Mary was not, even though she also doubted?

Zacharias had questioned the announcement made by Gabriel to him. Mary in her turn questioned the angel. Was unbelief at work in her? No. God reads hearts, and knows the spirit in which the creature speaks; Zacharias had spoken in the spirit of unbelief, Mary in that of inquiry. So the angel explained to her what she desired without one word of reproof. "The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee, therefore also that holy thing which shall be born shall be called the Son of God" (Luke 1:35). That pronoun uttered by God in Eden to the serpent, "her," i.e. the woman's "seed," a mysterious statement then, now received elucidation. The prophetic word, too, to Ahaz, the assurance that David's throne would not be supplanted by the son of Tabeal, was literally to come true, "Behold, a virgin shall conceive, and bear a son, and shall call His name Immanuel," etc. (Isa. 7:14). That virgin was Mary of Nazareth, and her Son was the woman's seed indeed, born of her, a pure virgin, by the mighty power of the Holy Ghost; and her Son would be the second man (1 Cor. 15:47), the head of a new race. Mary bowed to the divine will, "Behold the handmaid of the Lord; be it to me according to thy word." Gabriel's visit then ended, but not before he had told Mary of her cousin Elisabeth's expectations, of which she now evidently heard for the first time. The barren was to become fruitful. The virgin was to bear a son. Both were miraculous events. Elisabeth, however, could turn to her ancestress Sarah for a precedent. Mary could cite none for her case. Of that which God could do, if He was pleased, Sarah was of old an illustration. For the fulfilment of God's word in the Garden of Eden, Mary was the appointed vessel.

"But Mary said to the angel, How shall this be, since I know not a man?" She does not doubt, but she asks confidingly. Hence there is no smiting dumb nor any sign of unbelief, as in the case of Zacharias, who asked, "Whereby shall I know this?" There maybe a question in the spirit which needs an answer, but betrays no lack of faith. There might be one not so dissimilar in form, but which really sprang from unbelief. God does not judge according to appearance, but the heart.

The angel accordingly explains in all grace to Mary. "[The] Holy Spirit shall come upon thee,29 and power of [the] Highest overshadow thee." It was not to be nature, but Divine power. "Therefore the holy thing also which shall be born [of thee] shall be called Son of God," and not merely Son of man. This is exceedingly important. "Son of God" is a title that belongs to our Lord both in His Divine glory before He became a man and here; for, in this place when He became a man, He did not cease to be Son of God. As incarnate He was still the Son of God. So, again, when He rose from the dead, the same thing was true; He was the Son of God as risen again. It is plain therefore that it is a title that appertains to Him in the three conditions in which Scripture represents our Lord. He was the Son of God when He was purely and simply a Divine Person; Son of God when He became a man; Son of God when risen from the dead and gone out of this world to heaven. "Of thee," after "born" is supported only by C and a few minuscules.

But it is the conception that Mary does not understand. God permits her to ask the angel how this should be. Her question was according to God. I do not think there was any want of faith here. Zacharias had constantly asked for a son — it was only a question of the goodness and the power of God to perform his request — and was brought by the positive declaration of God to a point at which he had only to trust in it. He did not trust to the promise of God. It was only the exercise of the extraordinary power of God in the natural order of things. Mary asks, with holy confidence, since God thus favoured her, how the thing should be accomplished, outside the natural order. Of its accomplishment she has no doubt (see verse 45; "Blessed," said Elizabeth, "is she that believed.") She inquires how it shall be accomplished, since it must be done outside the order of nature. The angel proceeds with his commission, making known to her the answer of God to this question also. In the purposes of God, this question gave occasion (by the answer it received) to the revelation of the miraculous conception.

When God promised a son to Abraham, Sarah laughed within herself, doubting, not knowing the almighty power of the Promiser. Zacharias had also the difficulty of unbelief when he received from Gabriel the announcement that his wife Elizabeth should bear him a son. Mary replied to the angel, "How shall this be?" But although what was promised must be outside of the order of nature, it was not, as in the cases adduced, distrust that prompted her question. This is seen from the fact that Gabriel is permitted to give a full and complete answer to her inquiry, an answer which reveals two things, the miraculous conception of our blessed Lord, and that the Child so born should be called the Son of God, the Son of God as born into this world, according to the second psalm.* But to strengthen her divinely-given faith, which already existed, Gabriel was commissioned to inform her of God's grace also to her cousin Elizabeth, "for," said he, giving thus the unchanging basis of all belief, "with God nothing shall be impossible." God were not God if this were not so; and hence, too, as the Lord Himself taught, "All things are possible to him that believeth." It was this lesson which Mary had now learnt in her inmost soul, as shown by her response, "Behold the handmaid" (the bondsmaid) "of the Lord; be it unto me according to thy word."

A difficulty occurred to Mary's mind which she expressed in verse 34. The coming Child was to have David as His ancestor and yet be the Son of the Highest! She did not ask for a sign, since she accepted the angel's words, but she did ask for an explanation. How could this thing be? Mary's question and the angel's answer in verses 35-37, make quite plain in the third place the reality of the virgin birth and the wholly super-natural character of the Manhood of Jesus.

The Virgin's question "How shall this be, seeing that I know not a man?"--is not the result of unbelief. She believed, presupposing the absolute reality of the promise, in asking the exact manner of its fulfillment. The blessed mystery of the incarnation, how the Son of God should take on the human form and become man, is made known. It is a great mystery. "The Holy Spirit shall come upon thee" means that the human nature of our Lord was produced in the Virgin by a creative act of the Holy Spirit. (Matthew 1:18-20). And therefore He possessed an absolutely holy nature. "And the Power of the Most High shall overshadow thee." This is not a repetition of the first statement. It means that the Son of God, who is the Most High, overshadowed the Virgin, uniting Himself with the miraculously prepared human nature. He is designated in His Being "that holy thing" because He cannot be classified. And because He is holy there could be nothing in Him, who was born of the Virgin, which is unholy. And beautiful is the submission of the Virgin to the will of God.

The announcement of the birth of a son was not believed by Zacharias. Like Abraham and Sarah he looked to earthly circumstances. He did not reckon with the power of God. Disbelieving the words of Gabriel he was struck dumb. He should have shouted praises; instead, he expressed his doubt. Unbelief insults God; the character of God demands judgment upon unbelief.

"And Zacharias said to the angel, How shall I know this, for I am an old man, and my wife advanced in years?" Unbelief works just when God was about to accomplish this signal mercy — a remarkable but by no means infrequent case which we would do well to apply to our souls. That is, when God means mercy to us, we are too apt to limit the Lord; to doubt Him even when the blessing comes very close to us; to put some difficulty in the way, yielding to the suggestions of the enemy and the unbelief of our own hearts. Zacharias accordingly asks how he should know it.

The angel answers, "I am Gabriel23 who stand before God; and I have been sent to speak to thee and to bring these glad tidings to thee. And, behold, thou shall be silent, and not able to speak, till the day in which these things shall take place, because thou hast not believed my words, such as shall be fulfilled in their time." A measure of chastening was thus put upon Zacharias — a sign to others, but at the same time a rebuke to himself. The very fact that he was struck suddenly dumb would awaken the attention of the people. They would see that an extraordinary occurrence had taken place and might be led to think about it. On the other hand, when God had sent His angel to tell him that these things should be done, Zacharias showed his unbelief in requiring another sign. Hence his chastening. God's words should be fulfilled in their season spite of his unbelief. Mercy removes the stroke in due season.

The first and second chapters present us with facts concerning the birth of Christ, and with very interesting pictures of the godly remnant in Israel, out of whom, according to the flesh, He appeared. The first picture, verses 5-25, concerns the priest Zacharias and his wife. They were "righteous before God," from which we may deduce that they were a couple marked by faith, and consequently they were marked by obedience to the instructions of the law. Yet, when told by an angel that his elderly and barren wife should bear a son, he asked for a sign of some kind to be given in support of the bare Word of God. In this he proved himself to be an "unbelieving believer," though very true to type, for "the Jews require a sign" (1 Cor. 1:22); and he suffered governmentally, inasmuch as the sign granted was the loss of his power of speech. The sign was quite appropriate however. The Psalmist said, "I believed, therefore have I spoken." Zacharias did not believe, and therefore he could not speak.
