Fr. John Hardon, S.J. was very devoted to the Sacred Heart of Jesus and was a great promoter of the Apostleship of Prayer.
I had been thinking how it was too bad that he didn't live to see the current revival of the Apostleship and how that behind the revival is the devotion of many younger Jesuits to the Sacred Heart of Jesus.
But then it occurred to me: Fr. Hardon's intercession after he died is what's behind the current revival.
