The year before last I posted the following idea during the latter part of Lent. This year I wanted to put it up in time for folks to use it for the whole of Lent if they desired. It was given to me by my Pastor.
The idea is to choose 40 people who have been significant in your life and faith journey. Perhaps these are folks who have helped you "choose life." (If one has a smaller circle of significant friends and family, then one would list how ever many that really is.) Each of the 40 days of Lent one writes one of these people a note thanking them for who they are and what they have meant or do mean to you. (If your list is more modest, you could break the 40 days up and write notes at regular intervals.) During that day (or that period), you also pray for that person especially.
My thanks to my pastor for such a wonderful idea. How ever you decide to adapt the practice, I hope you will give it a try yourselves!
