What do Jews believe will happen one day (this is the biggest difference between Muslims, Christians, and Jews)?

Explanation:

The Jews believe in a messianic era that will bring about a resurrection of the dead and Day of Judgment. This will be followed by Olam Ha Ba -- a better “World to Come.” There are few absolutes in Judaism, and always much discussion and disagreement between rabbinical scholars. Some rabbis believe this Day of Judgment will happen after the resurrection, while others believe it is accomplished every year on Rosh Hashanah.
