You're assuming the conclusion. There is nothing deceptive about Jews for Jesus. There is something deceptive about being a Jew and not being for Jesus. The sceptre passed from Judah nearly two thousand years ago, so either the Messiah was Jesus or he never came, and Jews should disband their religion as having been based on false prophecies of a messiah who never came. The only way a person can continue to be a Jew is to believe that the Messiah did come when the prophet Daniel predicted, and the only conceivable candidate for messiahship at that time was Jesus.
Joe, you're treading on very dangerous ground with this. People can only live by their (hopefully informed) conscience. It is right to engage people to think about Jesus and who he is (including Jews), and to pursuade as best you can, but when you tell people they "should disband" you're encouraging the Jew-haters who will pick up on this, but fail to pick up on the love and compassion we are to exhibit to all, including the Jews. History is full of exactly this sort of thing, much to the shame of those of us who use the name "christian."
It took the Jews centuries to stop with the worship of the Baals and images and live out their belief in One God. But God is patient. It has taken even more centuries for the christians to understand that persecution of the Jews is wrong, and that is one of our most serious sins against God. But God is patient, and hopefully we are seeing now a way that we can disagree without disrepecting, persuade without persecuting. It's time for a new paradigm without sacrificing the universal message of the Gospel.
Keep close to Jesus.
