EXOD936 Life to-day issues a challenge to men of goodwill of all nations to unite and present the world with an ethical programme of conduct. In this task Judaism must play a conspicuous part. It was a Jewish teacher [Hillel the Elder] who, nearly two thousand years ago, made God exclaim to Israel [Sukk. 53a; this verse]: "If you come to My house, then shall I go to yours." Life will be worthwhile and safe only if our daily actions are motivated by holiness and if the heavenly pattern of life be reflected on earth. The aim of Jewish ethics is not to distinguish the Jew from among those around him so much by racial, social or political features but to mark him out by his spiritual characteristics.
