None of us lives for himself, and no one dies for himself. For if we live, we live for the Lord, and if we die, we die for the Lord; so then, whether we live or die, we are the Lord's. (Romans 14:7-8)So this from Hans Urs von Balthasar:
There are many ways in which even that death which is appointed for the body, although it is a physical event, can be assimilated in advance to that spiritual event that it is meant to be (and shall be, whether or not one wishes it to be), namely, the handing over of corporality to the Giver who fashioned the dust of the earth into a human instrument (Gen. 2:7). The Christian's attitude to the body will be governed by this final sacrifice, which he is to perform as a conscious act; even in health and active life he will make the coming final surrender of corporality the inner meaning of all his action.The word "instrument" is quintessential von Balthasar: Everyone is called to a specific mission, and every mission is inherently christological in nature and cruciform in structure. Christian faith leads not to the happiness we experience when we get our way, but to the joy that we experience when we realize that we were not meant to.
