From John Parsons at Hebrew for Christians:
God’s people are always “strangers” in this world; they are literally “e-stranged” — living here, yet not here. We are outsiders and pilgrims, not at home in this world, and our faith therefore is both a type of “protest” against any interpretation of reality that excludes, suppresses, denies, or minimizes the Divine Presence as well as a longing for the place where we truly belong…. If you feel crazy in an insane situation, then you are really quite sane… The world will feel oppressive and strange once you have been awakened from its madness and refuse to be moved by the delusions of the crowd… Life in olam hazeh (this world) is a place of passing that leads to the world to come. Our faith affirms that underlying the surface appearance of life is a deeper reality that is ultimately real and abiding. It “sees what is invisible” (2 Cor. 4:18) and understands (i.e., accepts) that the “present form of this world is passing away” (1 Cor. 7:31).
