It is not about a Devil’s Delusion but about man's delusion and human escape from his own responsible choices.
The Hebrew phrase tikkun olam (pronounced tee-KOON oh-LUHM) means "world repair." In modern Jewish circles, tikkun olam has become synonymous with the notion of social action and the pursuit of social justice. Created in the image of God each human being is requested to come close to the Bo're and to be a partaker of a marvellous peaceful world to which each member has to contribute out of free will. In order for the balance between good and evil intended by God to be restored, humans must be involved in the world's reparation and can not keep aside or aloof or 'do nothing' to get social justice or a better world.
Living in this world we should not be of it, but should be partakers of a Body that wants to be a Group of believers in One God, who want to offer themselves as repentant souls to the Most High and who want to create a place where they can gather and share their dreams in union with God and where all can grow stronger in their faith and become a people that shall be able to go through the big tribulation when it comes.
