I'm a Gentile Believer of the Messiah and embracing the Jewish roots of my faith. I have a burden for non-believing Jews, as well as Gentiles, and want to do my part in sharing the Word of Salvation.
The first followers of Jesus were Jews and they went through great lengths and even died to spread the gospel to the pagan Gentiles. Now it's our turn. As Christians we're doing a disservice to the Jews, as well as to God, by not preaching the gospel and spreading the word of Yeshua Ha'Mashiach (Jesus Christ) to God's chosen people.
By accepting the Messiah, you will not cease to being a Jew and become a Christian, but will become a "complete and fulfilled" Jew.
