Deeply-Rooted Doctrines

"Beloved, our condition needs much endurance; and endurance is produced when doctrines are deeply rooted. For as no wind is able by its assaults to tear up the oak, which sends down its root into the lower recesses of the earth, and is firmly clenched there; so too the soul which is nailed by the fear of God none will be able to overturn." (John Chrysostom, Homilies On John, 54:1)
