John 4:42: Verse 42
We have heard him ourselves - On seeing and hearing our Lord, the faith of those who had already believed on the woman's testimony was abundantly confirmed; and, besides those, may others believed who had not heard the woman speak.
This is indeed the Christ - The promised Messiah.
The Savior of the world - Not of the Jews only, but of the Samaritans, and of the whole Gentile world.
