"To struggle, yes, to continue to fight, to inflict blows and receive setbacks is in your power [when engaged in spiritual combat against your sins]. To uproot, however, belongs to God alone. If you could have done it on your own, what would have been the need for the coming of the Lord?"
- Pseudo-Macarius, 4th-century monastic writer, from his Fifty Spiritual Homilies (3:4)
