Hearts Open to My Mercy
Tell souls not to place within their own hearts obstacles to My mercy, which so greatly wants to act within them. My mercy works in all those hearts which open their doors to it. Both the sinner and the righteous person have need of My mercy. Conversion, as well as perseverance, is a grace of My mercy (Diary, 1577).
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
