From the Chief Rabbi:
Judaism is not an escape from the world but an engagement with the world. It is not "the opium of the people," as Karl Marx once called religion. It does not anaesthetise us to the pains and apparent injustices of life. It does not reconcile us to suffering. It asks us to play our part in the most daunting undertaking ever asked by G-d of mankind: to construct relationships, communities, and ultimately a society, that will become homes for the Divine presence. And that means wrestling with G-d and with men and refusing to give up or despair.
