Psalm 23, written by David around 2,900 years ago, is as true today for us as it was for David when he wrote it.  When you read it, pay attention to the pronouns "I" and "my".  Because Jehovah is my Shepherd, I don't need anything.  He is my care-giver, right now and always.  It's a personal relationship with me.  We do not want for anything as long as we have God.  We are like sheep and tend to wander off,  not sensing danger.  Sheep have no weapons or physical defenses.  They must be in the care of the shepherd.  As our good shepherd, the Lord gives us rest and living water.  He leads us to righteousness for Him.  In our greatest fears, we are not alone.  With God, we have goodness and mercy, not evil.  We will always live in God's house when we trust Him and obey Him, as we learn through the scriptures.  And, even better, we were given His Son, Jesus Christ, to seal our relationship with the Lord.  Praise God!  Travel light with the Lord as your Shepherd.
