Mark the Ascetic - On the Spiritual Law 39-42

39. Cease rebuking a man who has stopped sinning and who has repented. If you say that you are rebuking him in God's name, first reveal the evils in yourself.
40. God is the source of every virtue, as the sun is of daylight.
41. When you have done something good, remember the words 'without Me you can do nothing' (John 15:5).
42. Afflictions bring blessing to man; self-esteem and sensual pleasure, evil.
