We think we long for eternal life, but maybe what we're really longing for is perfect and unconditional love; a world in which lions actually do lay down with lambs; a world free of famines and floods, concentration camps and Gulag archipelagos; a world in which we grow up to love others in the same helplessly exuberant way we once loved our parents; a world in which we're forever adored like a precious baby; a world built on an entirely different logic from our own, one in which life needn't eat life in order to survive.
