A sign of true repentance is the acknowledgment that we deserve all the afflictions, visible and invisible, that come upon us, and even greater ones.

St. John Climacus

Take, in the next place, the subjection by which you subject the Son to the Father. What, you say, is He not now subject, or must He, if He is God, be subject to God? You are fashioning your argument as if it concerned some robber, or some hostile deity. But look at it in this manner: that as for my sake He was called a curse, who destroyed my curse; and sin, who takes away the sin of the world; and became a new Adam to take the place of the old, just so He makes my disobedience His own as Head of the whole body. 

As long then as I am disobedient and rebellious, both by denial of God and by my passions, so long Christ also is called disobedient on my account. But when all things shall be subdued unto Him on the one hand by acknowledgment of Him, and on the other by a reformation, then He Himself also will have fulfilled His submission, bringing me whom He has saved to God. For this, according to my view, is the subjection of Christ; namely, the fulfilling of the Father’s Will. But as the Son subjects all to the Father, so does the Father to the Son; the One by His Work, the Other by His good pleasure, as we have already said. And thus He Who subjects presents to God that which he has subjected, making our condition His own. Of the same kind, it appears to me, is the expression, ‘My God, My God, why hast Thou forsaken Me?’ It was not He who was forsaken either by the Father, or by His own Godhead, as some have thought, as if It were afraid of the Passion, and therefore withdrew Itself from Him in His Sufferings (for who compelled Him either to be born on earth at all, or to be lifted up on the Cross?) But as I said, He was in His own Person representing us. For we were the forsaken and despised before, but now by the Sufferings of Him Who could not suffer, we were taken up and saved. Similarly, He makes His own our folly and our transgressions; and says what follows in the Psalm, for it is very evident that the 22nd Psalm refers to Christ.

St. Gregory the Theologian

Only the foolish think that suffering is evil. A sensible man knows that suffering is not evil but only the manifestation of evil and healing from evil. Only sin in a man is a real evil, and there is no evil outside sin. Everything else that men generally call evil is not, but is a bitter medicine to heal from evil. The sicker the man, the more bitter the medicine that the doctor prescribes for him. At times, even, it seems to a sick man that the medicine is worse and more bitter than the sickness itself! And so it seems at times to the sinner: the suffering is harder and more bitter than the sin committed. But this is only an illusion – a very strong self-delusion. There is no suffering in the world that could be anywhere near as hard and destructive as sin is. All the suffering borne by men and nations is none other than the abundant healing that eternal Mercy offers to men and nations to save them from eternal death. Every sin, however small, would inevitably bring death if Mercy were not to allow suffering in order to sober men up from the inebriation of sin; for the healing that comes through suffering is brought about by the grace-filled power of the Holy and Life-giving Spirit. 

Blessed is the man who uses his sufferings, knowing that all suffering in this brief life is loosed on men by God in His love for mankind, for the benefit and assistance of men. In His mercy, God looses suffering on men because of their sins – by His mercy and not His justice. For, if it were by His justice, every sin would inevitably bring death, as the Apostle says: “Sin, when it is finished, bringeth forth death” (James 1: 15). In place of death, God gives healing through suffering. Suffering is God’s way of healing the soul of its sinful leprosy and its death.

St. Nikolai Velimirovich

He who accepts present afflictions in the expectation of future blessings has found the knowledge of the truth; and he will easily be freed from anger and remorse.

St. Kosmas Aitolos

Thanksgiving dulls the fierceness of your illness!  Thanksgiving brings the ailing person consolation!  The tutored heart, sweetened by thanksgiving, is renewed through the power of a living faith.  Illumined by the sudden light of faith, the mind begins to contemplate the divine Providence of God... The sickbed is often the place where one gains the knowledge of God and the knowledge of self.  The suffering of the body often brings spiritual joys, and the sickbed is often watered with tears of repentance and tears of joy in God.

St. Ignatius Brianchaninov

There is not, never has been, nor ever will be a place on the earth without sorrows.  A place without sorrows can only be in the heart, when the Lord is within it.

St. Nikon of Optina

But in dealing with all struggles as well as every virtue, patience is essential.  Not a single virtue can be accomplished without patience; it cannot be sustained without it.  He who is shaken in his virtue will not endure to the end and even that which was acquired will be lost.

St. Ignatius Brianchaninov

When struggles are replaced by consolations, and vice versa, they engender faith in God and indifference to the world.  Faith, having taken man by the hand, places him before God.

St. Ignatius Brianchaninov

What does it mean to take up your cross? It means the willing acceptance, at the hand of Providence, of every means of healing, bitter though it may be, that is offered. Do great catastrophies fall on you? Be obedient to God’s will, as Noah was. Is sacrifice demanded of you? Give yourself into God’s hands with the same faith as Abram had when he went to sacrifice his son. Is your property ruined? Do your children die suddenly? Suffer it all with patience, cleaving to God in your heart, as Job did. Do your friends forsake you, and you find yourself surrounded by enemies? Bear it all without grumbling, and with faith that God’s help is at hand, as the apostles did.

St. Nikolai Velimirovich

A continuously happy life produces extremely unhappy consequences. In nature we see that there are not always pleasant springs and fruitful summers, and sometimes autumn is rainy and winter cold and snowy, and there is flooding and wind and storms, and moreover the crops fail and there are famine, troubles, sicknesses and many other misfortunes. All of this is beneficial so that man might learn through prudence, patience and humility. For the most part, in times of plenty he forgets himself, but in times of various sorrows he becomes more attentive to his salvation.

St. Ambrose of Optina

The mercy of God is hidden in sufferings not of our choice; and if we accept such sufferings patiently, they bring us to repentance and deliver us from everlasting punishment.

St Mark the Ascetic

If you would be victorious, taste the suffering of Christ in your person, that you may be chosen to taste His glory. For if we suffer with Him, we shall also be glorified with Him. Blessed are you if you suffer for righteousness' sake. Behold, for years and generations the way of God has been made smooth by the Cross and by death. The way of God is a daily Cross. 

St Isaac of Syria
