When you judge others, you judge God. Whether you’ve seen a thief, a loose woman, or a drunkard sprawled on the street, do not judge, because the Lord allowed their passions. Through these they should find the path to God—they should be humbled, see their own powerlessness, come to know the Lord, and repent. And are you pleasing to God? That means the Lord in His grace and mercy is restraining your passions. Know that if He lets them go you will fall into worse sins, and perhaps you won’t manage to climb out of those sins and you’ll perish. There for be humble and cautious. You saw that a person sinned, but did you see later how he repented? Then don’t judge! Like a thread passing through the eye of a needle, so man experiences the same sin that he judged in another. 

—St. Gabriel the Fool for Christ of Samtavro
