Jesus Christ demands self-denial, that is, self-negation (Matt. 16:24; Mark 8:34; Luke 9:23), as a necessary condition of discipleship,. Self-denial is a summons to submit to the authority of God as Father and of Jesus as Lord and to declare lifelong war on ones instinctive egoism. What is to be negated is not personal self or ones existence as a rational and responsible human being. Jesus does not plan to turn us into zombies, nor does he ask us to volunteer for a robot role. The required denial is of carnal self, the egocentric, self-deifying urge with which we were born and which dominates us so ruinously in our natural state.
Jesus links self-denial with cross-bearing. Cross-bearing is far more than enduring this or that hardship. Carrying ones cross in Jesus day, as we learn from the story of Jesus own crucifixion, was required of those whom society had condemned, whose rights were forfeit, and who were now being led out to their execution. The cross they carried was the instrument of death. Jesus represents discipleship as a matter of following him, and following him as based on taking up ones cross in self-negation. Carnal self would never consent to cast us in such a role. “When Christ calls a man, he bids him come and die,” wrote Dietrich Bonhoeffer. Bonhoeffer was right: Accepting death to everything that carnal self wants to possess is what Christs summons to self-denial was all about.
