Some of my team and I recently finished a book entitled radical by David Platt.  

Warning: the content of this book is pleasantly disturbing and may be potentially life altering.  If you have any plans to live a high maintenance, low impact life, don't even think about picking up this book.  

Here's a few appetizing samples:

• "Real success is found in radical sacrifice"

• "Ultimate satisfaction is found not in making much of ourselves but in making much of God."

• "Meaning is found in community, not individualism; joy is found in generosity, not in materialism; and truth is found in Christ, not universalism."

Check out the book and the one year radical experiment.  I plan to walk our church through some of this material in the fall.
