God 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 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 SarovYou cannot be too gentle, too kind. Shun even to appear harsh in your treatment of each other. Joy, radiant joy, streams from the face of one who gives and kindles joy in the heart of one who receives.
Seraphim of SarovOh, if you only knew what joy, what sweetness awaits a righteous soul in Heaven! You would decide in this mortal life to bear any sorrows, persecutions and slander with gratitude. If this very cell of ours was filled with worms, and these worms were to eat our flesh for our entire life on earth, we should agree to it with total desire, in order not to lose, by any chance, that heavenly joy which God has prepared for those who love Him.
Seraphim of SarovThe Lord sometimes allows people who are devoted to Him to fall into such dreadful vices; and this is in order to prevent them from falling into a still greater sin-pride. Your temptation will pass and you will spend the remaining days of your life in humility. Only do not forget your sin.
