Psalm 23 is a panoramic view of the long march of human history set to music.  This is our story in poetic expression.  Life is a journey, and you have never been where you are going before.  Maybe   you think that all you need is a GPS, but you might want to think again.  The tough terrain of life needs more than a piece of technology.  From my perspective, we need a guide because we are going through a lot of dangerous territory up to and including death.  The journey can seem easy at the outset: green pastures; still waters; joyful, peaceful lives.  Then it turns harsh and  unrelenting: the valley of the shadow of death, the presence of   enemies, and then there’s the last mile on the road to home.  I have a recommendation: THE LORD IS MY SHEPHERD.
