Thou art the Son of God. That he acknowledges him to be the Son of God from his divine power is not wonderful; but on what ground does he call him King of Israel? for the two things do not appear to be necessarily connected. But Nathanael takes a loftier view. He had already heard that he is the Messiah, and to this doctrine he adds the confirmation which had been given him. He holds also another principle, that the Son of God will not come without exercising the office of King over the people of God. Justly, therefore, does he acknowledge that he who is the Son of God is also King of Israel And, indeed, faith ought not to be fixed on the essence of Christ alone, (so to speak,) but ought to attend to his power and office; for it would be of little advantage to know who Christ is, if this second point were not added, what he wishes to be towards us, and for what purpose the Father sent him. The reason why the Papists have nothing more than a shadow of Christ is, that they have been careful to look at his mere essence, but have disregarded his kingdom, which consists in the power to save. Again, when Nathanael calls him King of Israel, though his kingdom extends to the remotest bounds of the earth, the confession is limited to the measure of faith. For he had not yet advanced so far as to know that Christ was appointed to be King over the whole world, or rather, that from every quarter would be collected the children of Abraham, so that the whole world would be the Israel of God. We to whom the wide extent of Christ's kingdom has been revealed ought to go beyond those narrow limits. Yet following the example of Nathanael, let us exercise our faith in hearing the word, and let us strengthen it by all the means that are in our power; and let it not remain buried, but break out into confession.
Rabbi - Master. Applied appropriately to Jesus, and to no one else, Matthew 23:10.
The Son of God - By this title he doubtless meant that he was the Messiah. His conscience told him that he had judged right of his character, and that therefore he must know the heart and the desires of the mind. If so, he could not be a mere man, but must be the long-expected Messiah.
The King of Israel - This was one of the titles by which the Messiah was expected, and this was the title which was affixed to his cross, John 19:18. This case of Nathanael John adduces as another evidence that Jesus was the Christ. The great object he had in view in writing this gospel was to collect the evidence that he was the Messiah, John 20:31. A case, therefore, where Jesus searched the heart, and where his knowledge of the heart convinced a pious Jew that he was the Christ, is very properly adduced as important testimony.
Rabbi - That is, Teacher! and so this word should be translated.
Thou art the Son of God - The promised Messiah.
Thou art the King of Israel - The real descendant of David, who art to sit on that spiritual throne of which the throne of David was the type.
Nathanael answered and saith unto him,.... Being fully convinced of his omniscience by these instances:
Rabbi; that is, master, as it is interpreted in John 1:38, and is not here, because it is there:
thou art the Son of God; not by creation, for this would be to say no more of him, than may be said of every man; nor by adoption, for in that sense Nathanael himself was a Son of God, and many others; nor on account of his wonderful incarnation, which, it is very likely, at this time Nathanael knew nothing of; nor by reason of his resurrection from the dead, which, as yet, was not, and still less might be known by this person; nor because of his office, as Mediator, for this is expressed in the next clause; but by nature, as being of the same essence, and possessed of the same perfections God is; and of which he was convinced by the instances he gave of his omniscience; for it was from hence, and no other consideration, that he concludes him to be the Son of God: wherefore this phrase must be understood of him, not as Mediator, but as a divine person; as the natural, essential, and eternal Son of God; and who is truly and properly God: he adds,
thou art the King of Israel; having in view, no doubt, the passage in Psalm 2:6, where the characters of Son of God, and King of Zion, meet in the same person: not King of Israel, in a literal sense; though he was the son of David, and a descendant of his in a right line, and was of the royal line, and had a legal right to the throne of Israel; and Nathanael might have a view to this, being tinctured with the common national prejudice, that the Messiah would be a temporal prince: but his kingdom is not of this world; nor with observation; but is spiritual; and he is a King over Israel in a spiritual sense, even of saints, whether Jews or Gentiles: whom he conquers by his power, and rules in their hearts by his Spirit, and grace; and protects, and defends them from all their enemies.
Son of God . . . King of Israel--the one denoting His person, the other His office. How much loftier this than anything Philip had said to him! But just as the earth's vital powers, the longer they are frost-bound, take the greater spring when at length set free, so souls, like Nathanael and Thomas (see on John 20:28), the outgoings of whose faith are hindered for a time, take the start of their more easy-going brethren when loosed and let go.
Thou art the Son of God; the King of Israel. Philip had said, "Jesus, the son of Joseph," as he supposed, but Nathanael, convinced, declared him the Son of God. This is the first confession of the divinity of Jesus.
Nathanael answered - Happy are they that are ready to believe, swift to receive the truth and grace of God. Thou art the Son of God - So he acknowledges now more than he had heard from Philip: The Son of God, the king of Israel - A confession both of the person and office of Christ.
