Luke 1:16

“And many of the children of Israel,.... To whom only, or at least chiefly, he was sent, and came preaching, and administering the ordinance of baptism; and great multitudes of them flocked unto him, attended on his ministry, believed in his doctrine, and submitted to his baptism, but not all; for some slighted his preaching, and rejected his baptism: however, some there were, and many too, that were converted under his ministry, confessed their sins, and were baptized by him; which verified this prediction: shall he turn to the Lord their God; not Jehovah, the Father; for though he was the Lord God of the Jews in general, and of those that were turned by John's ministry in a special manner; yet John cannot be said "to go before him", as he is in the next verse; but the Messiah is here meant, who is the Lord Jehovah, and is often so called in the Old Testament; particularly in a prophecy afterwards respected, Isa 40:3 a name peculiar to God alone: and who also is called God, as he is frequently with additional epithets; as the mighty God, God over all, the great God, the true God, and eternal life; and our, your, and their God, the God of his covenant people, whether Jews or Gentiles; see Isa 25:9. Conversion, which is meant by turning to God, is not man's work, but God's; and is effected by his mighty power, which is only equal to it; but John was to be, and was, an instrument of the conversion of many among the Jews, by preaching the doctrine of repentance towards God, and faith in the Messiah, that was just ready to come: he was the means in the hand of God, of turning many from sin, of bringing them to a true sense of it, and to an hearty and ingenuous confession and acknowledgment of it; and from trusting to, and depending upon, their birth privileges, legal duties, and self-righteousness; and from their gross notions of a temporal Messiah; and of leading them to believe in Christ as a spiritual Saviour, as the Lamb of God, that should take away the sin of the world.”
