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 SarovEvery success in anything we should refer to the Lord and with the Prophet say: 'Not to us, O Lord, not to us, but to Your name give glory' (Ps. 113:9).
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 SarovWhen 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).
