"Judaism has brought into this world several ideas of great significance"

In a very general sense, it may be said that Judaism has brought into this world several ideas of great significance: 

Monotheism, directly or indirectly, wherever it is found and has influence in the world, and all that is implied by it or results from it, is derived from Judaism.

The idea of the Sabbath as a weekly day of rest also derives from Judaism.

As does the idea of the Messiah as an expectation of redemption in the time to come.

–Rabbi Adin Steinsaltz
