I just finished with the book 7: An Experimental Mutiny Against Excess by Jen Hatmaker. It is a convincing book. She began an experiment when she realized how much she had and began fasting from things to help bring her closer to God. And to listen what He wanted from her. She did 30 day fasts from things like media and spending. Lived with 7 pieces of clothing for a month. And spent a month praying the hours and taking a weekly Sabbaath.
By the end I was convicted. Do I really need to spend so much money when that money could be used to help more people? And my recycling has been pretty haphazard lately, so I am rinsing out my cans again. It will probably be a long time before I buy new clothes again.
This books is not a how to simplify type book. This is a "this is what I did" book that may inspire you to take action as well.
