 What we have, therefore, in the first two chapters of Luke, is God's vindication in the Lord Jesus presented as the One in whom He was ready to make good all His old pledges to Israel.

A priest is seen righteous according to the law, bus his wife without that offspring which the Jews looked for as the mark of God's favour towards them. Now God was visiting the earth in grace; and, as Zechariah ministered in the priest's office, an angel, even there a stranger, except for purposes of pity towards the miserable betimes (John 5:1-47), but long unseen as the witness of the glorious ways of God, announced to him the birth of a son, the forerunner of the Messiah. The unbelief even of the godly in Israel was apparent in the conduct of Zacharias; and God reproved it with inflicted dumbness, but failed not in His own grace. This, however, was but the harbinger of better things; and the angel of the Lord was despatched on a second errand, and re-announces that most ancient revelation of a fallen paradise, that mightiest promise of God, which stands out from all others to the fathers and in the prophets, and which, indeed, was to compass within itself the accomplishment of all the promises of God. He makes known to the virgin Mary a birth no way connected with nature, and yet the birth of a real man; for that man was the Son of the Highest a man to sit upon the throne, so long vacant, of His father David.
