Grace of God…

Bear in mind that one who is able to restrain himself or to do any other good thing does not do it by virtue of his own strength: it is the grace of God that empowers the person.
–The Desert Fathers (and Mothers)

Possess what God…

Many have indiscriminately afflicted their flesh and have come away empty, with nothing accomplished. Our mouth stinks from fasting; we have learned the Scriptures by heart; we have perfected [our knowledge of the Psalms of] David, and yet we do not possess what God is looking for, that is, fear, love, and humility.
