Keep our death in mind…

If we were to keep the imminence of our death in mind, we would never be overcome by sin: lust which is fleeting would not reign over us; we would never harbor anger against another human being; we would not love the possessions which pass away; and we would forgive every person who offended us. Therefore, beloved, let’s be zealous in carrying out the work we have committed ourselves to, and let’s travel to the end of the road on which we have begun our journey.
–Saint Athanasius the Great (c. 296-373)

Toil and sickness…

Just as wax that has not been warmed or softened cannot take the [imprint of the] seal set upon it, neither can the person acquire the strength of Christ unless he has been tried by bouts of toil and sickness.
–The Desert Fathers (and Mothers)
