The Lord commands all men to repent (Matt. 4:17), so that even the spiritual and those making progress should not neglect this injunction and fail to give attention to the smallest and most subtle errors.
By holy baptism original sin is expunged, as also sins committed before baptism. It also eliminates the violent power sin has over us till rebirth; it gives us the grace of the Holy Spirit by which we are united with God in Christ, and we receive power to subdue and conquer sin. For the simple reason that we are not delivered from the struggle with sin, we cannot be entirely free from sin during the whole of our earthly life, and even the righteous man may fall seven times (i.e. often) and rise again by repentance, says Scripture (Prov. 24:16). He falls on account of his weakness and limitations, because he does not always notice sin which subtly and imperceptibly rears its head from his fallen nature, and which is artfully and imperceptibly offered and suggested by fallen spirits. Repentance becomes his secure possession, his constant weapon, his invaluable treasure. By repentance the righteous man maintains his fellowship with Christ. He is healed by repentance from the wounds caused by sin.
The guarding of the conscience with regard to one’s neighbor is doing absolutely nothing at all that we know will upset or wound him, either by deed, word, gesture or even a glance. Even a gesture, can wound one’s neighbor. Briefly, man infects his conscience by deliberately doing those things that he knows will provoke his neighbor and will harm and embarrass him. Therefore, to keep one’s conscience and not act in this manner, is what we mean by keeping our conscience towards our neighbor.
Each one, in undertaking any task, should have this purpose in mind: to serve the need of others, not his own ends. In this way he will escape the charge of self-love, and will receive a blessing for his fraternal love from the Lord Who said: As long as you did it to one of these my least brethren, you did it to me (Mt. 25:40).
Those who have sinned must not despair. Let that never be. For we are condemned not for the multitude of evils, but because we do not want to repent...
Whoever repents sincerely is prepared to withstand any sorrow: hunger and homelessness, cold and heat, illness and poverty, humiliation and banishment, lies and slander, for the soul seeks God and does not concern itself with anything worldly, but instead prays with a clear mind.
Whatever gentleness you use in speaking with others, that very same gentleness will Christ use with you. With whatever measure you measure out to others, with that very same measure will He apportion out to you. Just as you forgive the failings of others, He forgives yours. With whatever love and gentleness you seek Him, likewise will He appear to you.
Our life and our death is with our neighbor. If we gain our brother, we have gained God, but if we scandalize our brother, we have sinned against Christ.
Therefore with your whole soul you should acknowledge yourself as worthy of enduring more than you already endure; remember the words which Christ the Savior spoke concerning a good deed done to one’s neighbor, words which should apply equally to every offensive word or deed against one’s neighbor. Whatever you have done to your neighbor, He says, you have done to Me.
There is no greater love than that a man lays down his life for his neighbor. When you hear someone complaining and you struggle with yourself and do not answer him back with complaints; when you are hurt and bear it patiently, not looking for revenge; then you are laying down your life for your neighbor.
When Christ commanded: 'Love your neighbor,' He did not think as many do, that it is necessary that we love only the good and the righteous and healthy and good-looking, but also the bad and the unrighteous and sick and leprous, and the hunchbacked and the blind and crazy and unattractive and repulsive and disgusting...
Remember, O my soul, the terrible and frightful wonder: that your Creator for your sake became Man, and deigned to suffer for the sake of your salvation. His angels tremble, the Cherubim are terrified, the Seraphim are in fear, and all the heavenly powers ceaselessly give praise; and you, unfortunate soul, remain in laziness. At least from this time forth arise and do not put off, my beloved soul, holy repentence, contrition of heart and penance for your sins.
