“…the grace of the Holy Spirit which is granted at baptism in the name of the Father and the Son and the Holy Spirit, in spite of man’s fall into sin, in spite of the darkness surrounding our soul, nevertheless shines in our hearts with the divine light (which has existed from time immemorial) of the inestimable merits of Christ. In the event of a sinner’s impenitence this light of Christ cries to the Father: “Abba, Father! Be not angry with this impenitence to the end (of his life).” Then, at the sinners conversion to the way of repentance, it effaces completely all trace of past sin and clothes the former sinner once more in a robe of incorruption spun from the grace of the Holy Spirit.”
(St. Seraphim of Sarov in ‘Conversations’)
