Only the gospel of Christ fully knows the mystery of sin and the problem of sin and everything which hides within it. The prodigal son of the Gospel is the perfect example of the repentant sinner. The Gospel shows us that man, through his free will, can share his life with Earth and with Heaven, with Satan and with God, with paradise and with hell. Sin gradually strips man of everything divine in him, paralyzes his every divine inclination and desire, until it finally throws him into the bosom of Satan. And then man reaches the plight of grazing the swine of his master, the Devil. The swine are passions, which are always greedy and gluttonous. In such a life, the unfortunate man is nothing more than insane. In a shocking parable of the Gospel, the Lord says about the prodigal son, ‘he came to himself,’ (Luke 15:17) How did he come to himself? He came to himself through repentance. Through sin, man becomes mad, insane. Every sin, even the most seemingly insignificant one, is always an insanity of the soul. Through repentance, man comes to his senses becomes complete again, comes to himself. Then he cries out loud to God, runs to Him, and cries towards Heaven, ‘Father, I have sinned against Heaven, and in thy sight’ (Luke 15:21). And what is the heavenly Father doing? He is always infinitely merciful upon seeing His child in a state of repentance. He has compassion for him, runs, embraces him, and kisses him. He orders His heavenly hosts, the holy angels: ‘Bring forth the best robe and put it on him; and put a ring on his hand, and shoes on his feet: and bring hither the fatted calf, and kill it; and let us eat, and be merry: for this is My son who was dead, and is alive again; and he was lost, and is found. And they began to be merry.’ (Luke 16:22-24) And this is taking place for each and every one of us, and for the sake of every sinner who repents. Namely, joy and happiness is taking place in the heaven of the All-merciful Lord and God, and together with Him, all of the holy angels.

St. Justin Martyr

What is the aim of the incarnate dispensation of God’s Word, preached in all the Holy Scriptures but which we, who read them, do not know? The only aim is that, having entered into what is our own, we should participate in what is His. The Son of God has become Son of Man in order to make us, men, sons of God, raising our race by grace to what He is Himself by nature, granting us birth from above through the grace of the Holy Spirit and leading us straightway to the kingdom of heaven, or rather, granting us this kingdom of heaven within us (Luke 17:21), in order that we should not merely be fed by the hope of entering it, but entering into full possession thereof should cry: our ‘life is hid with Christ in God’ (Col. 3:3).

St. Symeon the New Theologian

A terrible accident has a power to awaken us to the realization of the existence of various calamities and dangers surrounding us, from which the Providence of God preserves us. At the same time it convincingly persuades us to acknowledge our own infirmity and weakness and to seek the Father’s protection and His most powerful defense, which affirms us in the Wisdom and the Word of God, which came down from above by the will of the Heavenly Father under a curtain of flesh like ours, woven by the Divine Might from the Immaculate Virgin, for our salvation. He became man and taught us to pray that we be not led into temptation. This reminds us from what Father we have our existence, and this in turn should make us seek our heavenly Fatherland and our eternal inheritance.

St. Herman of Alaska

Where are You pasturing Your flock, O Good Shepherd, who carry the whole flock on Your shoulders? For the whole of human nature is one sheep, and You have lifted it upon Your shoulders. 

Show me the place of peace, lead me to the good pasture that will nourish me, call me by name so that I, Your sheep, may hear Your voice, and by Your speech give me eternal life. Answer me, You whom my soul loves. 

I give You the name “You whom my soul loves” because Your name is above every name and above all understanding, and there is no rational nature that can utter it or comprehend it. Therefore Your name, by which Your goodness is known, is simply the love my soul has for You. How could I not love You, when You loved me so much, even though my heart was black, that You laid down Your life for the sheep of Your flock? A greater love cannot be imagined than exchanging Your life for my salvation. 

Show me then (says my soul) where You pasture Your flock, so that I can find that saving pasture too, and fill myself with the food of heaven without which no one can come to eternal life, and run to the spring and fill myself with the drink of God. You give it, as from a spring, to those who thirst—water pouring from Your side cut open by the lance, water that, to whoever drinks it, is a fountain of water springing up to eternal life. 

If You lead me to pasture here, You will make me lie down at noon, sleeping at peace and taking my rest in light unstained by any shade. For the noon has no shade and the sun stands far above the mountain peaks. You bring Your flock to lie in this light when You bring Your children to rest with You in Your bed. But no one can be judged worthy of this noonday rest who is not a child of light and a child of the day. Whoever has separated himself equally from the shadows of evening and morning, from where evil begins and evil ends, at noon he will lie down and the sun of righteousness will shine on him. 

Show me, then (says my soul), how I should sleep and how I should graze, and where the path is to my noonday rest. Do not let me fall away from Your flock because of ignorance and find myself one of a flock of sheep that are not Yours. 

Thus spoke my soul, when she was anxious about the beauty that God’s care had given her and wanted to know how she could keep this good fortune forever.

St. Gregory of Nyssa

If you do good, you must do it only for God. For this reason you must pay no attention to the ingratitude of people. Expect a reward not here, but from the Lord in heaven. If you expect it here — it will be in vain and you will endure deprivation.

St. Ambrose of Optina

Thou, O Christ, art the Kingdom of Heaven; 

Thou, the land promised to the meet; 

Thou, the meadowland of Paradise; 

Thou, the hall of the celestial banquet; 

Thou, the ineffable bridal chamber; 

Thou, the table set for all; 

Thou, the bread of life; 

Thou, the unheard-of drink; 

Thou, both the urn for the water and the life giving water; 

Thou, moreover, the inextinguishable lamp for each one of the saints; 

Thou, the garment and the crown and the One Who bestoweth the crowns; 

Thou, the joy and rest; 

Thou, the delight and glory; 

Thou, the gladness and mirth; 

And Thy grace, the grace of the Spirit of all sanctity, will shine like the sun in all the saints; 

And Thou, the unapproachable Sun, wilt shine in their midst, and all will shine brightly, according to the measure of their faith, their asceticism, their hope and their love, their purification, and their illumination by Thy Spirit.

St. Symeon the New Theologian

He who shall preserve the life bestowed upon him, and give thanks to Him Who imparted it, shall receive also length of days forever and ever. But he who shall reject it, and prove himself ungrateful to his Maker, inasmuch as he has been created, and has not recognized Him Who bestowed the gift upon him, deprives himself of the privilege of continuance forever and ever. And, for this reason, the Lord declared to those who showed themselves ungrateful towards Him: ‘If you have not been faithful in that which is little, who will give you that which is great?’ (cf. Lk. 16:11) indicating that those who, in this brief temporal life, have shown themselves ungrateful to Him Who bestowed it, shall justly not receive from Him length of days forever and ever.

St Irenaeus of Lyon
