John 4:42

John GILL Expositor
The Saviour of the world: they knew him to be the Saviour, he who was spoken of as such; for his work to bruise the serpent’s head implies it, and his name Shiloh imports as much: and besides, he is called by Jacob God’s salvation, Gen 49:18. God appointed him as a Saviour; he sent him, and he came as such, and is become the author of salvation; and his name is called Jesus, on this account: and a great Saviour he is; both able, and willing; and he is suitable to the case of sinners; and is a complete, and an only one: and these Samaritans knew him to be "the Saviour of the world"; not of every individual person in it, for all are not saved by him; nor of the Jewish world, for many of them died in their sins; but of the Gentiles, in distinction from the Jews; see Joh 3:16; 1Jo 2:2; even of all God’s elect, whether among Jews or Gentiles; of all that believe in him, of whatsoever nation, and in whatsoever state and condition: so that their knowledge of him, and faith in him, were beyond that of the Jews, who looked upon the Messiah only as a Saviour of their nation; and that the Gentiles would have no manner of benefit and advantage by him: though the Jews {b} do call the angel in Exo 23:20, "the Saviour", or "Redeemer of" the world. And this the Samaritans might know from the writings of Moses, as from Gen 22:18 49:10 their present knowledge of Christ was not a mere notional, speculative, and general one, but was special, spiritual, and saving, which they had from the spirit of wisdom and revelation in the knowledge of Christ; they approved of him as their Saviour; they trusted in him as such; they had an experimental acquaintance with him, and practically owned him; and which they attained to by hearing him.
