Richard Foster, author of “Celebration of Discipline” writes a chapter called “Simplicity”. In it, he says,
…freedom from anxiety is one of the inward evidences of seeking first the kingdom of God. The inward reality of simplicity involves a life of joyful unconcern for possessions. Neither the greedy nor the miserly know this liberty. It has nothing to do with abundance of possessions or their lack. It is an inward spirit of trust.
Foster describes simplicity in terms of avoiding “duplicity” (having more than one item that serves the same general function). Spurring trend. Not chasing technology. Protecting the rights of the underpaid worker by careful choices. Knowing the joy of using things until they wear out. Waiting on God to give things so that we value them (Amen, how I know that). Sharing with freedom. Not focused on having or not having. Learning to be content with little or with much. Unaffected.
