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... 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 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.
