Do you try an practice Sabbath rest regularly?  Has it been a struggle?  Is Sabbath rest even a part of your vocabulary?  Wherever you may be on the topic what is inescapable is this: Sabbath rest is a Biblical command.  Sabbath rest is something, as followers of Jesus, we are called to pursue.  This article by Tim Keller is a great starting point for focusing our understanding and practice of Sabbath rest.  I commend it to you for your study and to begin integrating Sabbath into your weekly rhythms.
