13 But the angel said to him, " Do not be afraid , Zacharias , for your petition has been heard , and your wife Elizabeth will bear you a son , and you will [1]give him the name John . 14 "You will have joy and gladness , and many will rejoice at his birth . 15 "For he will be great in the sight of the Lord ; and he will drink no e wine or liquor , and he will be filled with the Holy Spirit [2]while yet in his mother's womb . 16 "And he will turn many of the sons of Israel back to the Lord their God . 17 "It is he who will go as a forerunner before Him in the spirit and power of Elijah , TO TURN THE HEARTS OF THE FATHERS BACK TO THE CHILDREN , and the disobedient to the attitude of the righteous , so as to make ready a people prepared for the Lord ." 18 Zacharias said to the angel , "How e will I know this for certain? For I am an old man and my wife is advanced in [3]years ."

The father and mother of John the Baptist were sinners as all are, and were justified and saved in the same way as others; but they were eminent for piety and integrity. They had no children, and it could not be expected that Elisabeth should have any in her old age. While Zacharias was burning incense in the temple, the whole multitude of the people were praying without. All the prayers we offer up to God, are acceptable and successful only by Christ's intercession in the temple of God above. We cannot expect an interest therein if we do not pray, and pray with our spirits, and are not earnest in prayer. Nor can we expect that the best of our prayers should gain acceptance, and bring an answer of peace, but through the mediation of Christ, who ever lives, making intercession. The prayers Zacharias often made, received an answer of peace. Prayers of faith are filed in heaven, and are not forgotten. Prayers made when we were young and entering into the world, may be answered when we are old and going out of the world. Mercies are doubly sweet that are given in answer to prayer. Zacharias shall have a son in his old age, who shall be instrumental in the conversion of many souls to God, and preparing them to receive the gospel of Christ. He shall go before Him with courage, zeal, holiness, and a mind dead to earthly interests and pleasures. The disobedient and rebellious would be brought back to the wisdom of their righteous forefathers, or rather, brought to attend to the wisdom of that Just One who was coming among them. Zacharias heard all that the angel said; but his unbelief spake. In striking him dumb, God dealt justly with him, because he had objected against God's word. We may admire the patience of God towards us. God dealt kindly with him, for thus he prevented his speaking any more distrustful, unbelieving words. Thus also God confirmed his faith. If by the rebukes we are under for our sin, we are brought to give the more credit to the word of God, we have no reason to complain. Even real believers are apt to dishonour God by unbelief; and their mouths are stopped in silence and confusion, when otherwise they would have been praising God with joy and gratitude. In God's gracious dealings with us we ought to observe his gracious regards to us. He has looked on us with compassion and favour, and therefore has thus dealt with us.
