Where there is God, there is no evil. Everything coming from God is peaceful, healthy and leads a person to the judgment of his own imperfections and humility.
Seraphim of SarovMore Seraphim of Sarov quotes
The Lord sometimes allows people who are devoted to Him to fall into such dreadful vices; and this is in order to prevent them from falling into a still greater sin-pride. Your temptation will pass and you will spend the remaining days of your life in humility. Only do not forget your sin.
Seraphim of Sarov
