I knew a person to whom our Lord revealed the result of a mortal sin and who said she thought no one who realized its effects could ever commit it, but would suffer unimaginable torments to avoid it. This vision made her very desirous for all to grasp this truth, therefore I beg you, my daughters, to pray fervently to God for sinners, who live in blindness and do deeds of darkness.
– St. Teresa of Avila
