John 1:15

John bare witness of him, saying, This is he, &c. “This might probably happen at the time when Jesus made his first appearance among those that came to be baptized by John; when, at his offering to receive his baptism, though John before had been a stranger to him, and knew him not by any personal acquaintance with him, yet, by some powerful impression on his mind, he presently discerned that this was He whom he before had taught the people to expect, and of whose person he had given them so high a character. For it was plainly from his knowledge of him, that John at first would have declined baptizing him as an honour of which he looked upon himself to be unworthy. Nor is it to be doubted, that when first he knew the person, of whose appearance he had raised such expectations by his preaching, he would immediately be ready to acquaint his hearers, that this was he who was intended by him; which they themselves might have been ready to conclude from the uncommon veneration and respect with which the Baptist treated him, who had been always used to treat men with the greatest plainness.” He that cometh after me is preferred before me Namely, by God. “Erasmus supposes, that John here refers to the honours which he knew had been paid to Jesus in his infancy, by the angel who announced his birth to the shepherds; by the shepherds themselves; by the eastern sages; by Simeon and Anna; honours which could not be paralleled by any thing which had happened to him. But the words seem to have a more extensive meaning, comprehending the superior dignity of Christ's nature, office, commission, and exaltation, as Mediator. See Matthew 3:11, the passage here referred to. For he was before me It is fit that Jesus should be raised above me, because he is a person superior in nature to me. For though he was born after me, he existed before me.” “This must undoubtedly refer to the state of glory in which Christ existed before his incarnation, of which the Baptist speaks so plainly, John 3:31.” See Doddridge and Macknight.
