Psalm 121

Psalm 121 
English Standard Version (ESV) 

   This is a good one to memorize.  It's short, simple and to the point:  The Lord will be with you.
  Remember that scene in Peter Pan, when Peter is fighting his shadow, then has to work to have it reattached.  It's absurd because of the basic premise:  our shadow is always with us.  In the same way, Christ is always with us, and he will not sleep, not even for a moment, lest your soul be in mortal danger.
  Now, you may fear that in the darkest of nights, your shadow abandons you until the light returns.  Instead, Christ draws closer still.  Often, in these dark nights, we cease to look for the presence of God, but if we take a moment to remember the promises of God, we can trust that God will be there, with us in the darkness, and he can lead us forward, for to God, even the darkness is like light.

  You have nothing to fear.  God is with you.  Take courage, be strong, and you shall live with God forever.
