אות-עב

Regarding the matter of strengthening — that a person must know that it is impossible for him in any way to know in this world where he truly stands and holds, and this is the essence of his free choice and his test — only he must strengthen himself in faith, to believe even regarding himself that no good movement of his is ever lost, G-d forbid, as our sages of blessed memory said. (See: Faith, Ois 101)
