Fighting Satan in the Heart
"The most important work that a spiritual wrestler can do, is to enter within the heart, there to fight Satan; to hate and repel the thoughts that he inspires and to wage war upon him."
- St. Makarios of Egypt. "Fighting Satan in the Heart." The Art of Prayer: An Orthodox Anthology, Timothy Ware, Editor, Faber & Faber, 1966, p. 201.
