“The knowledge of correct dogmas is in the mind, and it is often fruitless, arrogant, and proud… The true faith in Christ is in the heart, and it is fruitful, humble, patient, loving, merciful, compassionate, hungering and thirsting for righteousness; it withdraws from worldly lusts and clings to God alone, strives and seeks always for what is heavenly and eternal, struggles against every sin, and constantly seeks and begs help from God for this.”
(St. Tikhon of Zadonsk, ‘The Gospel and Faith’)
