Abstract: By combining T.S.Eliot's life experiences with his thought exploration and his final belief in Christianity, this paper studies his consciousness of redemption which is expressed in his representative work Waste Land systematically.In Waste Land, Eliot considers the western modern society enters into a spiritual and cultural crisis without reason, belief and order after the First World War, and only by rebuilding Christian faith the western modern society could be saved could.But his religious thought has a limitation and fails finally because the Christian concept couldn't adapt to modern waste world.However, Eliot's effort isn't in vain.Maybe it is just the no alternative situation tells us that we should open up a new way to save the modern waste world, and it is our further exploration on Eliot's, the giant's shoulders.
