A challenge for those of the Christian faith (I am not presuming that there are not followers of other faiths on this board).
There are a number of Messianic prophecies outlined in the OT that Jesus did not fulfill.
They include:
- world peace did not come at the time of Jesus (Isaiah 2:1-4)
- the entire world did not acknowledge G-d as the one true G-d (Zechariah 14:9)
- the Holy Temple was not rebuilt (Ezekiel 37: 26-28)
- and Jesus did not gather the Jewish people from all of the earth to land of Israel (Isaiah 11:10-12).
There's' a bunch more, but these are a good example.
