Athanasius of Alexandria, on Ps 89:9

“For all our days are spent; and in thy wrath we have fainted away. Our years shall be considered as a spider:”

“Let everyone above all have this zeal in common so that having made a beginning they not hesitate or grow fainthearted in their labors or say, "We have spent a long time in ascetic discipline." Instead, as though we were beginning anew each day, let each of us increase in fervor. For the entire lifetime of a human being is very brief when measured against the age to come; accordingly, all our time here is nothing compared with life eternal. Everything in the world is sold according to its value and things of equal value are exchanged, but the promise of eternal life is purchased for very little. For it is written, "The days of our life are seventy years or, if we are strong, perhaps eighty; more than this is pain and suffering." When we persevere in ascetic discipline for all eighty or even one hundred years, we will not reign for the equivalent of those one hundred years. Instead of a hundred years, we will reign forever and ever. And although we are contested on earth, we will not receive our inheritance here; we have promises in heaven instead. Once more: when we lay aside this perishable body we receive it back imperishable. LIFE OF ST.”
