Hiding our Weakness

One of my twin lambs has an eye infection.  I'm treating her with antibiotics and keeping her, her sibling and her mother isolated.  Needless to say, I'm keeping an eagle eye on the rest of the lambs.  Sheep can be very tricky because they show no weakness or illness until they are nearly ready to drop dead.  A good shepherd must know her sheep very well to notice any slight changes that might indicate the onset of an illness or injury, because the sheep will use every effort to conceal it.  By the time a sheep is noticeably ill, it is often too late to save her. Some people think sheep have no "will to live" because from their view the sheep is suddenly sick and usually dead within 24 hours.  They say, "I started medicating the sheep, but she died anyway."  In reality, the sheep had been ill for some time but hiding her illness from the world.
  I think we are a lot like sheep trying to hide our weaknesses and sins from the world, and from our Good Shepherd.  We must confess our weakness to our Good Shepherd so that He can heal us while there is still time.
