Have you ever bumped your toe, banged your knee, or walked into a wall? I’m not talking about pain that comes from being a walking phone-zombie, but rather from the blindness that comes about from walking in the dark. Walking without sight presents great challenges. Those with good eyesight only experience those challenges rarely. But those experiences provide great lessons for us. It should not surprise us that God uses the physical realities of blindness to teach far more important spiritual lessons.
