These things I have spoken unto you, that in me you might have peace. In the world you shall have tribulation: but be of good cheer; I have overcome the world.

Cyprian of Carthage
AD 258
Thus Job, after the loss of his wealth, after the death of his children, grievously afflicted, moreover, with sores and worms, was not overcome, but proved; since in his very struggles and anguish, showing forth the patience of a religious mind, he says, "Naked came I out of my mother's womb, naked also I shall go under the earth: the Lord gave, the Lord hath taken away; as it seemed fit to the Lord, so it hath been done. Blessed be the name of the Lord.".
Forsake our patrimonies, undergo imprisonment, bear chains, spend our lives, endure the sword, the wild beasts, fires, crucifixions-in fine, all kinds of torments and penalties, to be endured in the faith and courage of patience; as the Lord Himself instructs us, and says, "These things have I spoken unto you, that in me ye might have peace. But in the world ye shall have tribulation; yet be confident, for I have overcome the world.".
And again: "These things have I spoken unto you, that in me ye may have peace; but in the world ye shall have tribulation: but be of good confidence, for I have overcome the world.".
Also according to John: "These things have I spoken unto you, that in me ye may have peace. But in the world ye shall have affliction; but have confidence, for I have overcome the world."
