St. Mark the Ascetic writes about sins that do overcome even good Christians and monks. These are the kinds of sins we might commit daily, sins we assume everyone commits, sins which are part of human nature. They are sins nevertheless from which we are to repent and to replace them with Christian virtues. They are sins from which we are to abstain, especially during Great Lent. St. Mark laments that:
“They were secretly enticed and overcome by
malicious envy, by jealousy that hates everything good,
by strife, quarreling, hatred, anger,
bitterness, rancor, hypocrisy,
wrath, pride, self-esteem,
love of popularity, self-satisfaction,
avarice, listlessness,
by sensual desire which provokes images of self-indulgence,
by unbelief, irreverence, cowardice,
dejection, contentiousness, sluggishness, sleep,
presumption, self-justification, pomposity,
boastfulness, insatiateness, profligacy,
greed, by despair which is the most dangerous of all,
and by the subtle workings of vice”
(The Philokalia, Kindle Loc. 4273-78).
