'The lord of this world is a rod of chastisement and a
scourge to beginners in the spiritual life. Yet, as has been said, he
brings them great glory and added honor because of the afflictions and
trials they endure. In this way he helps them to attain the state of
perfection, while he prepares even greater and harsher punishment for
himself. In short, something most beneficial is brought about through
him: as has been said, evil, while intending what is not good,
contributes to the good. For, in souls whose intention is sound, even
that which appears harmful results in something good. As St. Paul says:
'All things work together for good to them that love God.' (Rom. 8:28)
It is on this account that the rod of chastisement was permitted, so that through it, as in a furnace, the vessels might be more rigorously fired; but those unequal to the test, being easily broken, are rejected as faulty, since they cannot endure the heat of the fire. Being a servant and the Lord's creation, the devil tests and afflicts people, not as he thinks fit or desires, but to the extent that his Master allows him. Knowing the exact nature of everything, God permits each person to be tested according to his strength. As St. Paul puts it: 'God is to be trusted not to let you be tried beyond your strength, but with the trial He will provide a way out, so that you are able to bear it.' (1 Cor. 10:13)'
