For he that is mighty hath done to me great things,.... With respect to the incarnation of Christ, a new, a great, and unheard of thing; in causing her, though a virgin, to conceive; and also to bear such a Son, who should be called Jesus, a Saviour, Immanuel, God with us; and who was no other than the mighty God, the everlasting Father, and Prince of Peace: wherefore she describes God the author of it, by a proper periphrasis of him, "he that is mighty"; since this was a work of almighty power, and very justly adds, and holy is his name: seeing this was brought about without any impurity, through the overshadowing influence of the Holy Ghost; whereby the human nature was preserved from the infection of sin, was sanctified, and fit to be united to the Son of God, and to be a sacrifice for the sins of his people. This may also have regard to the great things God had done for her in a spiritual sense; in the choice of her to eternal life, in the redemption of her by the Messiah, and in her regeneration and sanctification; wherein God had displayed his sovereign grace and goodness, and his almighty power, in a way consistent with his justice and holiness.
