First, a Christian merely shares the message of the Gospel - any conversion is done by God.
Second, as you well know, Jesus was Jewish. Christianity is based on the fulfillment of the Jewish prophecy of a Messiah. The difference between Jews and Christians is that Christians believe that Jesus IS that Messiah while Jews do not. Although, obviously some Jews have and do believe. Peter was a Jew and the focus of his ministry was to preach the Gospel to Jews. (Paul's was targeted at non-Jews).
It is understandable that some Jews today might characterize Christianity as just "another religion" and the use of the word "sects" betrays the author's bias. The reality is that Judaism and Christianity, while separate, are inseparable. Islam, although an Abrahamic religion, is much more distant and any bundling of it with Christianity, when separating religions from Judaism, is misleading at best.
Having said all that, I, as a Christian, believe that the Jews are the chosen people God. I can believe that without be inconsistent. Further, I do not see a conversion of a Jew to Christianity as contradictory with God's plan. On the contrary, it is completely consistent with Biblical (both Old and New Testament) teaching.
One of the things I find fascinating about Jewish belief and practice (among those who reject their Messiah Yeshua (Jesus)that is) is this LACK of proselytization. If Judaism IS the truth, and the rest of religions, including Christianity are distortions of the truth, you'd think for the love of others Jews would WANT to tell us that. I mean Christianity, according to Jewish thought, is actually blasphemy--in that we call a mere man, God ... If that doesn't condemn us in this life, surely it should in the next, correct? Why the entire lack of concern for the rest of humanity, being content just to practice Judaism while the rest of the world can go to hell?
On the other hand if perhaps other religions ARE good for other peoples, doesn't that simply say contemporary Jewish belief may very well be wrong? One way for God's chosen people and other ways for everyone else? Seems a very schizophrenic view of human nature...
Jesus directly fulfilled in detail HUNDREDS of messianic prophecies from the Torah--its too bad most Jewish people can't handle facing that and know their Messiah.
Just one further thought: As Christians, we have been grafted into the root of the tree of Abraham (Rom 11:17), and although we remain "wild shoots" not inclined to follow all the traditions and teachings held by Jews, they are nonetheless our brothers and sisters and should be treated with all respect. Paul in fact gives a warning to that effect in Rom 11:21 when he said, "For if God did not spare the natural branches, He will not spare you either."
Almighty God is able to save whomever He will without our interference or "help". No crusade is needed. No sharp words need be exchanged over points of theology. Love, respect and charity are far more powerful than any sword.
From where, exactly, do you get this notion, that JEWS are the "chosen people of God"?
My reading of scripture tells me that ISRAEL are the chosen of God, not solely the Jews.
Furthermore, all who take up the Cross and follow Jesus Christ are partakers in the promise given to Abraham. In essence, then, those who believe in Christ and follow Christ's teachings are "Israel".
Many Jews are inheritors of the traditions of those who effectively reject Christ (as this news story illustrates), and as such are "no better than infidels." That is, they have no claim on the promise of God to His chosen people.
Anyone who is not of Christ is, in essence, "a gentile," no matter what their ETHNIC origin.
So do I, but the story doesn't end there. Click on my Profile to see who else was "chosen", at the same time and same place.
