Letter 463

Isidore of PelusiumUnknown|isidore pelusium
From: Isidore of Pelusium, monk at Pelusium
To: Paul the Presbyter
Date: ~410 AD
Context: Isidore on the virtue of patient perseverance — the soul that continues steadily toward the good is building something permanent, even when the daily progress seems invisible.

The work of virtue is done slowly, Paul — so slowly that it sometimes seems nothing is happening. But this is the nature of all genuine building. The foundation is invisible once the house stands; the daily practice is invisible once the character is formed. What you are constructing through patient perseverance is not nothing, even when you cannot see it.

The soul that presses forward without spectacular moments of breakthrough, that simply continues day after day in what is right and refuses to give ground — that soul is building something that will last. Do not grow weary of the slow work. It is the only kind that produces what endures.
