You worship that which you don't know. We worship that which we know; for salvation is from the Jews.
Salvation is from the Jews ... God took hold "of the seed of Abraham"  (Hebrews 2:16); the Jews were custodians of the Scripture  (Romans 3:2); Christ was born "under the law."  The Old Testament Scriptures are they which "testify" of Christ (John 5:39).  Even the church today is the Israel of God, and all Christians are "the seed of Abraham"  (Galatians 3:29).  In the sense of origins and the typical nature of the Jewish religion, it is still true that "salvation is of the Jews."
