Saints are sinners

"Pray passionately to God, the Lord, for the greatest and most necessary of gifts: to see one's own sins and to weep over them. Whoever has this gift has everything." Igumen Nikon

Isaiah 6
In the year that King Uzziah died, I saw the Lord seated on a throne, high and exalted, and the train of his robe filled the temple. Above him were seraphs, each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying. And they were calling to one another: "Holy, holy, holy is the LORD Almighty; the whole earth is full of his glory."

At the sound of their voices the doorposts and thresholds shook and the temple was filled with smoke.

"Woe to me!" I cried. "I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the LORD Almighty."

Then one of the seraphs flew to me with a live coal in his hand, which he had taken with tongs from the altar. With it he touched my mouth and said, "See, this has touched your lips; your guilt is taken away and your sin atoned for."
