Take graces for others
And I will tell you one more thing—take these graces not only for yourself, but also for others; that is, encourage the souls with whom you come in contact to trust in My infinite mercy. Oh, how I love those souls who have complete confidence in Me — I will do everything for them (Diary, 294).
Devotion to the souls in Purgatory contains in itself all the works of mercy, which supernaturalized by a spirit of faith, should merit us Heaven. de Sales
