Luke 1:45

And blessed is she that believed..... Meaning Mary, a woman, a very young woman, and who had had things very incredible to nature and reason told her; and yet she believed, without objecting thereto, or requiring a sign; tacitly referring to the unbelief of Zacharias, who was a man, a man in years, a priest by office; and yet had been very incredulous, in a thing that was much more possible; because there had been instances of it before, in Sarah, Hannah, and Manoah's wife; than what was related to the virgin, of which there had been none; and which to reason, and with men, was impossible: and happy indeed is every one, that has true faith in any degree; for faith is the faith of God's elect, and is both a fruit and evidence of electing grace, which is the source of all blessings; it is the gift of God, and the operation of his Spirit, and can never be lost: many are the blessings such as believe are in the possession of, and openly entitled to; as the justification of their persons, the remission of their sins, their adoption into the household of God, liberty at the throne of grace, and a right to the eternal inheritance; they enjoy much solid peace, joy, and comfort in their own souls; bring much glory to God, and shall be saved in the Lord, with an everlasting salvation:for there shall be a performance of those things which were told her from the Lord: these words may be considered, either as the subject matter of her faith, and be rendered in connection with the former, thus, "blessed is she that believed, that there shall be a performance, &c", being fully persuaded, that what the angel had told her, concerning the conception and birth of a son, concerning his name, and the greatness of his person, and the nature, extent, and duration of his kingdom, should be certainly and punctually fulfilled; or as a reason of her happiness, because there should be a sure accomplishment of them.
