Why did Jesus Say, Salvation is of the Jews?

What did Jesus mean when he said, 'Salvation is of the Jews'? Jesus spoke this to a Samaritan woman who was not a Jew. At Jesus' time salvation was of the Jews because no other religion had the oracles of YHVH God. So Jesus came to seek and save the lost Gentiles, and the lost Jews. Jesus brought reformation to Judaism, which changed under Jesus' influence - so it again would be a channel for God's saving grace. And for the non-Jew, Jesus didn't come to start a new Christian Religion, Jesus came to gather that other flock (non-Jews) to his flock (Judaism) (John 10:16). so there would be one flock with one shepherd. All Jesus told us to do for salvation, is what Judaism practices; keeping YHVH 'law and the Prophets' (Matthew 5:17-20) and to worship YHVH alone (Matthew 4:10). Those in the Christian Church do neither because they have been deceived by the 'most cunning of beast', the serpent beast from the Garden of Eden. All of this and much more I will share in this book.
