When we are dissatisfied with things as they are, or suffer and know pain, we begin to imagine what the world would be like if things were different—if there were no hunger or thirst and all tears were wiped away (Rev. 7:17).
Creative imagination reaches toward God, and glimpses a new heaven and new earth. The new reality has nothing to do with the present order. In fact, the one who responds to call seeks to put something more beautiful in the place of what she sees. This is where the friction and fight begin.
