When a man receives something Divine, in his heart he rejoices; but when he receives something diabolic, he is disturbed. The Christian heart, when it has received something Divine, does not demand anything else in order to convince it that this is precisely from the Lord; but by that very effect it is convinced that this is heavenly, for it senses within itself spiritual fruits: love, joy, peace, and the rest (cf. Gal. 5:22).
Seraphim of SarovThose who have truly decided to serve the Lord God should practice the remembrance of God and uninterrupted prayer to Jesus Christ, mentally saying: Lord Jesus Christ, Son of God, have mercy on me, a sinner.
Seraphim of SarovWhat are you to us, you who are cut off from God, a fugitive for Heaven, and a slave of evil? You dare not do anything to us: Christ, the Son of God, has dominion over us and over all. Leave us, you thing of bane. We are made steadfast by the uprightness of His Cross. Serpent, we trample on your head.
Seraphim of Sarov... the people who, in spite of the bonds of sin which fetter them and hinder them (by constraint and by inciting them to new sins), come to Him, our Savior, with perfect repentance for tormenting Him, who despise all the strength of the fetters of sin and force themselves to break their bonds ? such people at last actually appear before the face of God made whiter than snow by His grace. 'Come, says the Lord: Though your sins be as scarlet, I will make them whiter than snow' (Isa. 1:18).
Seraphim of SarovThe reading of the word of God should be performed in solitude, in order that the whole mind of the reader might be plunged into the truths of the Holy Scripture, and that from this he might receive warmth, which in solitude produces tears; from these a man is wholly warmed and is filled with spiritual gifts, which rejoice the mind and heart more than any word.
