The cross of Jesus Christ is the deathblow to the notion of finding fulfillment in this world and on its terms. Jesus said that it is only he who hates his life in this world who will gain real life (John 12:25). He calls us to take up our cross to follow Him (Matt. 16:24), and to do it daily (Luke 9:23).
