This is not a matter of subjective theory, but of plain, historical fact. If there had never been a nation of Israel, there would have been no patriarchs, no prophets, no apostles, no Bible and no Saviour. In John 4:22, Jesus Himself summed all this up in one simple statement: "Salvation is from the Jews." Christians from all other racial backgrounds owe to the Jewish people a spiritual debt which can never be calculated.
