I think this is a very beautiful sentiment/idea for a funeral/death remembrance card.  The idea of a child knocking at/on the door of the tabernacle is a charming sentiment, and mimics the “let the children come unto Me”.  The prayer on the back of the card is also nice.  “Be not severe in Thy judgment but let some drops of Thy Precious Blood fall upon the devouring flames…”   May we keep this on our minds as we pray for the deceased, and for Mr. Petrilli!
