But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law, When the fullness of the time was come - The time which God in his infinite wisdom counted best; in which all his counsels were filled up; and the time which his Spirit, by the prophets, had specified; and the time to which he intended the Mosaic institutions should extend, and beyond which they should be of no avail.
God sent forth his Son - Him who came immediately from God himself, made of a woman, according to the promise, Genesis 3:15; produced by the power of God in the womb of the Virgin Mary without any intervention of man; hence he was called the Son of God. See Luke, Luke 1:35, and the note there.
Made under the law - In subjection to it, that in him all its designs might be fulfilled, and by his death the whole might be abolished; the law dying when the Son of God expired upon the cross.
