We Share in the Suffering of the Poor Souls in Purgatory

Thank you, Mr. Flanders for this beautiful article which so eloquently describes the compassion we MUST have for the Suffering Souls in Purgatory AND for those who are steeped in sin in this life. We should daily offer to God the Father, through the most pure hands of Our Sorrowful Mother the Most Precious Blood which poured forth from the thousands of wounds of Our Divine Lord, in reparation and for the conversion of poor sinners in this life and for the alleviation of the sufferings of those who are in Purgatory. We are ALL poor sinners and speaking from personal experience, we will become what we mock if we have not the Heart of Christ, desiring not the death of the sinner, but that he or she change their ways and live.

If you perform these prayers without knowledge of the indulgence, do you still receive the benefits?
