A newly arrived soul in heaven was met by St. Peter. The saint toured the soul around heaven. Both of them walked side by side inside a large workroom filled with angels. St. Peter stopped in front of the first section and said, "This is the Receiving Section. Here, all the petitions to God said in prayer are received. The soul looked at the section, and it was terribly busy with so many angels sorting out petitions written on voluminous paper sheets from all over the world. They walked again until they reached the second section. "This is the Packaging and Delivery Section. Here, the graces and blessings asked for are packed and delivered to those who asked for them down on earth." Oh, how busy it was! There were many angels working in that room, since so many blessing were being packed and delivered to earth. Finally at the farthest corner of the room, the soul stopped at the last section. To the surprise of the soul, only one angel was there, hardly doing anything. "This is the Acknowledging Section," St. Peter told the soul. "How is it that there is no work here?" St. Peter answered, "That's the sad thing. After people receive the blessings they asked for, very few send their acknowledgments." "How does one acknowledge God's blessings?" "Simple," St. Peter answered, "Just say, 'Thank you, Lord'."
