Men who love God are so far from complaining of their sufferings, that their complaint and their suffering is rather because the suffering which God's will has assigned them is so small. All their blessedness is to suffer by God's will, and not to have suffered something, for this is the loss of suffering. This is why I said, Blessed are they who are willing to suffer for righteousness, not, Blessed are they who have suffered.
All that a man bears for God's sake, God makes light and sweet for him...
If all was right with you, your sufferings would no longer be suffering, but love and comfort.
If God could have given to men anything more noble than suffering, He would have redeemed mankind with it: otherwise, you must say that my Father was my enemy, if he knew of anything nobler than suffering.
True suffering is a mother of all the virtues.
