5 At the present time then, a man is angry with us, a man of like passions, and of like soul, and we are afraid: but in the case of Job it was an evil and malignant demon who was angry; nay, he was not simply angry, but set in motion all sorts of machinations, and brought forward every stratagem; and yet even with all he could not conquer the fortitude of the just man. But here is a man, who is at one time angry, at another time is reconciled; and we are nevertheless dead with fear.
On that occasion it was a devil that waged war, who is never reconciled to human nature, but has engaged in a war without treaty, and a battle without truce against our race; yet nevertheless, the just man laughed his darts to scorn. What apology then, or what pardon can be ours, if we cannot sustain a human trial; we who are taught such spiritual wisdom under grace; when this man before grace, and before the Old Testament, endured this most grievous war so nobly! These things, beloved, we should therefore always discourse of with one another; and by words of this kind encourage ourselves.
For you are witnesses, and your conscience is a witness how much gain we have already received from this trial! The dissolute man has now become sober; the bold man meek; the slothful man active. They who never at any time saw a church, but constantly spent their time at the theatre, now remain in the church the whole day long. Tell me then, do you grieve on this account, that God has made you earnest through fear; that He has led you by tribulation to a sense of your own safety?
But is your conscience pained? Yea, is your mind pierced every day as with a dart, expecting death, and the greatest wrath? Nevertheless, from thence too we shall gain a great advance toward virtue, if our piety is made more earnest by means of the distress. For God is able to free you from all these evils this day. But not until He sees that you are purified; not until He sees that a conversion has taken place, and a repentance firm and unshaken, will He entirely remove the tribulation.
The goldsmith, until he perceives the gold well refined, will not draw it out from the furnace; and even so God will not take away this cloud before He has thoroughly amended us. For He Himself who has permitted this trial, knows the time for removing it. So it is also with one who plays the harp; he neither overstrains the string, lest he break it, nor relaxes it too much, lest he mar the consonance of its harmony. Thus does God act. He neither places our souls in a state of constant repose, nor of lengthened tribulation; making use of both these at His discretion; for he neither suffers us to enjoy continual repose, lest we should grow listless, nor on the other hand does he permit us to be in constant tribulation, lest we sink under it, and become desperate.
