Prophecies unfulfilled
>The whole world will worship the One God of Israel. Isaiah 2:11-17, Isaiah 40:5, Zephaniah 3:9
Currently large swaths humanity do not worship the One God of Israel.
>Knowledge of God will fill the world. Isaiah 11:9, 45:23, 66:23, Jeremiah 31:33, Zechariah 3:9, 8:23, 14:9,16, Ezekiel 38:23, Psalm 86:9
Note that this is knowledge of God - not simply unsubstantiated faith in God. Even amongst the faithful, such knowledge is rare.
>All Israelites will be returned to their homeland Isaiah 11:12, 27:12-13, Ezekiel 11:17, 36:24, Deuteronomy 30:3
Though there are more Jews today living in the Land of Israel than there have been since the exile began nearly 2,000 years ago - there is still a large diaspora consisting of millions of Jews.
>The Jewish people will experience eternal joy and gladness. Isaiah 51:11
The Jewish people have been historically subject to a great degree of persecution (the Holocaust, the Inquisition, pogroms, etc.) and while generally our condition has improved, we are still a perpetual target.
>Nations will recognize the wrongs they did to Israel. Isaiah 52:13-53:5
While modern Germany as a nation-state does much to repent of its history (i.e. the Holocaust), various states and human institutions with much blood and guilt on their hands, to this day either remain silent, white-wash/cover up history, or in some perverse instances even exult in it.
>The peoples of the world will turn to the Jews for spiritual guidance. Zechariah 8:23
While there is today an emerging interest in observance of the Noahide laws (the Torah's universal laws of man), there still has not been an en masse turn towards learned Torah observant Jews for guidance in spiritual matters.
