They say that Abba Macarius the Egyptian [St. Macarius the Great] on one occasion went up from Scete to the Nitrian mountain, and as he drew near to a certain place, he said to his disciple, "Pass on a little in front of me"; and when he had done so there met him a certain heathen priest, who was running along and carrying some wood about the time of noon. And that brother cried out to him and said, "O minister to devils, where run thou?"  And the priest turned round and smote him with many severe blows, and he left him with but very little breath remaining in him, and he took up his wood and went on his way; and when he had gone on a little further the blessed Macarius met him on his journey, and said to him, "May you be helped, O man of labours?"  And the priest was astonished, and came to him and said, "What fair thing have you seen in me that you should salute me [in this gracious fashion] ?"  And the old man said to him, "I see that you toil, and that you do not know that you are toiling for naught"; then he said to the old man, "At your salutation I also was very sorry, and I learned that you did belong to the Great God. But a wicked monk met me just before you didst, and he cursed me, and I smote him even to death."  And the old man knew that it was his disciple [of whom he spake], and the priest laid hold upon the feet of Macarius, and said to him, "I will not let you [go] until you make me a monk"; and they came to the place where the brother was lying, and they carried him and brought him to the church of the mountain. Now when the fathers saw the heathen priest with him, they marvelled that he had been converted from the error which he had held; and Macarius took him and made him a monk, and through him many of the heathen became Christians. And Abba Macarius said, " ' An evil word makes wicked even those who are good, and a good word makes good even those who are wicked,' as it is written."

from Sayings of the Holy Desert Fathers

My friends, God does not ask or desire that man should mourn from sorrow of heart, but rather that, out of love for Him, he should rejoice with spiritual laughter. Remove the sin, and the tear of sorrow is superfluous for your eyes.

St. John Climacus

Do not be surprised that you fall every day; do not give up, but stand your ground courageously. And assuredly, the angel who guards you will honour your patience. While a wound is still fresh and warm, it is easy to heal…

St. John Climacus

Thomas, one of the twelve, called the Twin, was not with them when Jesus came. He was the only disciple absent; on his return he heard what had happened but refused to believe it. The Lord came a second time; He offered His side for the disbelieving disciple to touch, held out His hands, and showing the scars of His wounds, healed the wound of his disbelief. 

Dearly beloved, what do you see in these events? Do you really believe that it was by chance that this chosen disciple was absent, then came and heard, heard and doubted, doubted and touched, touched and believed? It was not by chance but in God’s providence. In a marvelous way God’s mercy arranged that the disbelieving disciple, in touching the wounds of his Master’s body, should heal our wounds of disbelief. 

The disbelief of Thomas has done more for our faith than the faith of the other disciples. As he touches Christ and is won over to belief, every doubt is cast aside and our faith is strengthened. So the disciple who doubted, then felt Christ’s wounds, becomes a witness to the reality of the resurrection. 

Touching Christ, he cried out: ‘My Lord and my God. 

Jesus said to him: ‘Because you have seen me, Thomas, you have believed.’ 

Paul said: ‘Faith is the guarantee of things hoped for, the evidence of things unseen.’

It is clear, then, that faith is the proof of what can not be seen. What is seen gives knowledge, not faith. When Thomas saw and touched, why was he told: ‘You have believed because you have seen me?’ 

Because what he saw and what he believed were different things. God cannot be seen by mortal man. Thomas saw a human being, whom he acknowledged to be God, and said: ‘My Lord and my God.’ 

Seeing, he believed; looking at one who was true man, he cried out that this was God, the God he could not see. What follows is reason for great joy: ‘Blessed are those who have not seen and have believed.’ 

There is here a particular reference to ourselves; we hold in our hearts One we have not seen in the flesh. We are included in these words, but only if we follow up our faith with good works. The true believer practices what he believes. But of those who pay only lip service to faith, Paul has this to say: ‘They profess to know God, but they deny him in their works.'

St. Gregory the Great

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

Open, O doors and bolts of my heart, that Christ the King of Glory may enter! 

Enter, O my Light, and enlighten my darkness; 

Enter, O my Life, and resurrect my deadness;

Enter, O my Physician, and heal my wounds; 

Enter, O Divine Fire, and burn up the thorns of my sins; 

Ignite my inward parts and my heart with the flame of Your love; 

Enter, O my King, and destroy in me the kingdom of sin; 

Sit on the throne of my heart and alone reign in me, O Christ, my King and Lord!

St Dimitri of Rostov 

The soul is greater than the body: the body becomes sick, and with that it is finished. But a spiritual sickness extends into eternity. Deliver us, O Lord, from such illness, and grant us healing.

St Macarius of Optina

You alone I follow, Lord Jesus, Who heals my wounds. For what shall separate me from the love of God, which is in You? Shall tribulation, or distress, or famine? I am held fast as though by nails, and fettered by the bonds of charity. 

Remove from me, O Lord Jesus, with Your potent sword, the corruption of my sins. Secure me in the bonds of Your love; cut away what is corrupt in me. Come quickly and make an end of my many, my hidden and secret afflictions. Open the wound lest the evil humor spread. With Your new washing, cleanse in me all that is stained. 

Hear me, you earthly men, who in your sins bring forth drunken thoughts: 

I have found a Physician. He dwells in Heaven and distributes His healing on earth. He alone can heal my pains Who Himself has none. He alone Who knows what is hidden can take away the grief of my heart, the fear of my soul: Jesus Christ. Christ is grace! Christ is life! Christ is resurrection! Amen.

St Ambrose of Milan
