Write down everything that occurs to you regarding My goodness. I answered, “What do You mean, Lord, what if I write too much?” And the Lord replied, My daughter, even if you were to speak at one and the same time in all human and angelic tongues, even then you would not have said very much, but on the contrary, you would have sung in only a small measure the praises of My goodness — of My unfathomable mercy.
O my Jesus, You Yourself must put words into my mouth, that I may praise You worthily.
My daughter, be at peace; do as I tell you. Your thoughts are united to My thoughts, so write whatever comes to your mind. You are the secretary of My mercy. I have chosen you for that office in this life and the next life (Diary, 1605).

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
