Helping care for my 4-yr-old granddaughter has been an interesting adventure.  Three days a week she is in a preschool program from 8-12.  That means she is up early to have breakfast, dress, get her stuff together and leave home about 7:45.  At noon she comes home, has lunch, and NEEDS a nap.  But, oh, how she fights that nap time.  So many excuses from whining,  "I need a drink of water." to "I have to go potty."  As her "Grannymother," I can see a huge benefit in just an hour's worth of nap time and rest.  She is much more pleasant at dinner time and into the evening when she rests for a while. We can even enjoy her company, if she has had a nap, but oh how she resists! 
As leaders of ministry in our churches, do we allow God to see the big picture for us and usher us into a time of afternoon rest?  Do we heed the wisdom of those wiser than ourselves when they offer us a nap time? Do we offer excuses about how we can keep going with just a sip of water or a short bathroom break instead of a refreshing rest?  I wonder, how many times our unpleasantness is a result of just being too tired?  There are times when we are called to keep going but I pray we can hear God's knowing call to rest and refreshment along our ways, whether it is spoken out loud by those with whom we serve or when it comes in the gentle voice of God's Spirit at work within us.
