The saints were people like all of us. Many of them came out of great sins, but by repentance they attained the Kingdom of Heaven. And everyone who comes there comes through repentance, which the merciful Lord has given us through His sufferings.
– St. Silouan the Athonite, Writings
Do not forsake prayer, for just as the body becomes weak when it is deprived of food, so also the soul when it is deprived of prayer draws nigh to weakness and noetic death.
– St. Gennadius of Constantinople, The Golden Chain
