There are moments when even a person wholly devoted to this world and
to the things of the flesh awakens from the slumber which possesses
him. He suddenly sees everything clearly, he sees that his previous
life on earth was nothing but a chain of errors, weaknesses,
transgressions, betrayals of God, that his actions were naturally the
seeds of future punishments and that all his virtues will not
withstand the gaze of the Eternal Judge. Beholding all this, he
condemns himself, trembling to the core of his being, and,
disillusioned with himself, through this despair turns with hope to
God. This disposition towards repentance is nothing but the “rushing
of a mighty wind” which precedes the descent of the Holy Spirit (Acts
2:2).

- Archbishop Theophan of Poltava, from a sermon at Pentecost
