Mark the Ascetic - On the Spiritual Law 43-46

43. He who suffers injustice escapes sin, finding help in proportion to his affliction.
44. The greater a man's faith that Christ will reward him, the greater his readiness to endure every injustice.
45. By praying for those who wrong us we overthrow the devil; opposing them we are wounded by him.
46. Better a human than a demonic sin. Through performing the Lord's will we overcome both.
