"In my bedroom cupboard I have stashed three boxes that I call my prayer boxes: not unlike a sewing basket with accumulated buttons and bright bits of cloth and thread, they represent a collected treasure trove of things that remind me to pray....reminders to pray for certain people; cards with specific prayers or quotations about prayer worth remembering; small pamphlets with radio messages by people such as Billy Graham on subjects like Christian conversion and prayer; church notices that have meant something special to my prayer life....

"I might find in my prayer boxes a postcard of El Greco's painting 'The Purification of the Temple,' acquired on a visit to the Frick Collection in New York, or I might find Salvador Dali's 'The Sacrament of the Last Supper,' from the National Gallery of Art in Washington, D.C."

To Practice: Make a prayer box for yourself or for your entire household. For beginners, what objects would you put there?
