Those 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 Sarov... only the good deed done for Christ's sake brings us the fruits of the Holy Spirit. All that is not done for Christ's sake, even though it be good, brings neither reward in the future life nor the grace of God in this life. That is why our Lord Jesus Christ said: 'He who gathers not with Me scatters' (Lk. 11:23).
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 SarovGod is a fire that warms and kindles the heart and inward parts. Hence, if we feel in our hearts the cold which comes from the devil - for the devil is cold - let us call on the Lord. He will come to warm our hearts with perfect love, not only for Him but also for our neighbor, and the cold of him who hates the good will flee before the heat of His countenance.
Seraphim of SarovIn spite of our sinfulness, in spite of the darkness surrounding our souls, the Grace of the Holy Spirit, conferred by baptism in the name of the Father and the Son and the Holy Spirit, still shines in our hearts with the inextinguishable light of Christ ... and when the sinner turns to the way of repentance the light smooths away every trace of the sins committed, clothing the former sinner in the garments of incorruption, spun of the Grace of the Holy Spirit. It is this acquisition of the Holy Spirit about which I have been speaking.
