It is no accident that you are at this place.  You haven't been here before because you weren't ready (maybe desperate enough) to embrace it as a person grabs a life jacket from a sinking ship.  Now you want it.  You need it.  You are ready to do whatever it takes to get your life back.  

Ironically, we all could have enjoyed it much earlier but it usually takes our own drivenness to bring us to the place of desperate emptiness.  Be aware of the danger of blaming others for the place you now find yourself. Burn out tends to start by pointing to others and saying, "This is somehow your fault..."  

The beauty of brutal honesty is surrendering at the place where we confess, "Lord, this is my fault.  I failed to grasp the significance of Sabbath.  I built my life on the affirmations of others.  I pushed hard to do your work for you.  And I failed to understand that all you invited me to do was grow into you."

One of the Biblical discoveries (John 1) is in the teaching of Logos.  It is literally saying that Jesus is the presence of the life of God.  It isn't simply that we find meaning in Jesus.  It is the fact that Jesus created life itself.  It is far more powerful than I had understood.  Jesus is what we would call "life."  When he teaches that he "has come that we might have life," and when he says, "I am the way, the truth and the life;" he isn't simply referring to the fact that salvation is found in him.  He is saying that my very existence is dependent upon him. My sense of meaning and purpose is dependent upon him. Every inquiry I make into the spiritual plain is directed through him.  He is the mediator - the "switchboard operator" who directs my soul's longing to its ultimate source.

That is your Sabbath rest's purpose.  You are being drawn back to life, new life.  Life that isn't limited to your ability and charm.  It is additional life that flows from a source you are beginning to recognize but yet to understand.  Sabbath teaches you to learn how to drink deeply, rest completely, live "abandonedly".  That is my prayer for you.  

Burn out can hold anger, resentment, frustration.  Rather than trying to rid yourself of it, embrace it.  Thank God for it.  It only reveals in greater depth, the truth of our own ugliness.  That in itself is a wonderful gift because it reminds us that "apart from him, I can do nothing." "All my efforts amount to nothing more than a filthy rag."  To know that fully frees us to die completely and be reborn as a child nurtured by God himself. That is a gift - so are our weaknesses.
