And yet another.

"We must be willing to accept the bitter truth that, in the end, we may have to become a burden to those who love us. But it is necessary that we face this also. The full acceptance of our abjection and uselessness is the virtue that can make us and others rich in the grace of God. It takes heroic charity and humility to let others sustain us when we are absolutely incapable of sustaining ourselves. 

We cannot suffer well unless we see Christ everywhere—both in suffering and in the charity of those who come to the aid of our affliction."
