Though there are very many nations all over the earth, ...there are no more than two kinds of human society, which we may justly call two cities, ...one consisting of those who live according to man, the other of those who live according to God ....To the City of Man belong the enemies of God, ...so inflamed with hatred against the City of God.
You have found that you were more secure before you accumulated so much. See what greed has imposed on you: You have filled your house and now you fear burglars. You have hoarded money and lost sleep. See what greed has commanded you: "Do this!" And you did it.
You have been professing yourself reluctant to throw off your load of illusion because truth was uncertain. Well, it is certain now, yet the burden still weighs you down, while other people are given wings on freer shoulders, people who have not worn themselves out with research, nor spent a decade and more reflecting on these questions.
What art Thou then, my God? what, but the Lord God? For who is Lord but the Lord? or who is God save our God? Most highest, most good, most potent, most omnipotent; most merciful, yet most just; most hidden, yet most present; most beautiful, yet most strong; stable, yet incomprehensible; unchangeable, yet all-changing; never new, never old; all-renewing, and bringing age upon the proud, and they know it not; ever working, ever at rest; still gathering, yet nothing lacking; supporting, filling, and overspreading; creating, nourishing, and maturing; seeking, yet having all things.
For why, my brothers and sisters, would you rejoice in silver? Either your silver will perish, or you will, and no one knows which will perish first. For neither can you remain here always, nor can silver remain here always; so also with gold, wardrobes, houses, money, real estate-and in the end, even the light by which we enjoy all these things. So do not be willing then to rejoice in such things as these. Rejoice instead in the light that has no setting; rejoice in the dawn which no yesterday precedes, and no tomorrow follows.
For you [God] are infinite and never change. In you "today" never comes to an end: and yet our "today" does come to an end in you, because time, as well as everything else, exists in you. If it did not, it would have no means of passing. And since your years never come to an end, for you they are simply "today."
Trials and tribulations offer us a chance to make reparation for our past faults and sins. On such occasions the Lord comes to us like a physician to heal the wounds left by our sins. Tribulation is the divine medicine.
