For I bear the Jews witness that they have a zeal for God, but not according to knowledge.
Romans 10:2

Even today, the rabbis spend their lives studying Torah, but only through the lenses of man-made traditions that continue to blind them to the truth. They sincerely want to know YHWH, but fail for this blindness.

Christians portray the Messiah as a lawless anti-Messiah, and since the Jewish people are strongly discouraged and sometimes even forbidden from reading the New Testament for themselves, they believe this lie and so are still unable to recognize him. Like Joseph, his true identity is hidden behind a Gentile façade. Some day, also like Joseph, Yeshua will open their eyes. They will believe and repent, and then they will be restored to God’s grace and to their full inheritance.
