Mark Scandretti, in his wonderful book, Practicing the Way of Jesus introduces an exercise called Have2Give1. This exercise follows the teaching of Jesus in Luke 3:11 that for those who have two of something, they should share with the one who has none. Look through your belongings and find the things you have two of, then seek someplace to give away one of the two. It could be an individual or an organization like goodwill. Make it a constant practice to give away anything that you unnecessarily have two of.
