Five years ago Dr. J. Matthew Sleeth and his family lived in a big house, had two luxury cars, loads of money, and lots of stuff. As chief of the medical staff at a large hospital, Sleeth was living the American dream—until he realized that something was terribly wrong. As he saw patient after patient suffering from cancer, asthma, and other chronic diseases, he began to understand that the Earth and its inhabitants were in trouble. Feeling helpless, he turned to his faith for guidance. He discovered how the timeless lessons of personal responsibility, simplicity, and stewardship taught in the Bible could be applied to modern life.
Excerpt from Serve God, Save the Planet by Sleeth:
"Over the past five years, my family and I have made significant lifestyle changes. We no longer live in our big house; instead, we have one the exact size of our old garage. We use less than one-third of the fossil fuels and one-quarter of the electricity we once used. We've gone from leaving two barrels of trash by the curb each week to leaving one bag every few weeks. We no longer own a clothes dryer, garbage disposal, dishwasher, or lawn mower. Our "yard" is planted with native wildflowers and a large vegetable garden. Half of our possessions have found new homes. We are a poster family for the downwardly mobile.
Because of these changes, we have more time for God. Spiritual concerns have filled the void left by material ones. Owning fewer things has resulted in things no longer owning us. We have put God to the test, and we have found his Word to be true. He has poured blessings and oppurtunities upon us. When we stopped living a life dedicated to consumerism, our cup began to run over. We have seen miracles."
I am currently reading Serve God, Save the Planet and have found it to be very convicting. Others who are recommending this book include: Brian McLaren and Shane Claiborne.
