Death has power, but because of the victory of Christ, it’s power is rather limited. Here, Bonhoeffer argues convincingly that we idolize death today by ascribing it far too much power. His description of how the secular west is both seemingly extremely concerned about life (health, children, the future, etc.) and, at the same time, also flippant about it is quite seems entirely accurate to me.
Where death is the last thing, fear of death is combined with defiance. Where death is the last thing, earthly life is all or nothing. Boastful reliance on earthly eternities goes side by side with a frivolous playing with life. A convulsive acceptance and seizing hold of life stands cheek by jowl with indifference and contempt for life. There is no clearer indication of the idolization of death than when a period claims to be building for eternity and yet life has no value in this period, or when big words are spoken of a new man, of a new world and of a new society which is to be ushered in, and yet all that is new is the destruction of life as we have it. The drastic acceptance or rejection of earthly life reveals that only death has any value here. To clutch at everything or to cast away everything is the reaction of one who believes fanatically in death.
But wherever it is recognized that the power of death has been broken, wherever the world of death is illumined by the miracle of the resurrection and of the new life, there no eternities are demanded of life but one takes of life what it offers, not all or nothing but good and evil, the important and the unimportant, joy and sorrow; one neither clings convulsively to life nor casts it frivolously away. One is content with the allotted span and one does not invest earthly things with the title of eternity; one allows to death the limited rights which it still possesses. It is from beyond death that one expects the coming of the new man and of the new world, from the power by which death has been vanquished.
