“The LORD is my Shepherd; I shall not want. He makes me to lie down in green pastures: He leads me beside the still waters.” Psalm 23:1-2 (KJV)
I have never had any thing to do with sheep. I am so ignorant of sheep, that I must rely upon what I have read by written by others and what I can see in fields that I pass occasionally. Sheep need a shepherd to care for them. People are likened to sheep in Scripture at times. In this first verse of the best known Psalm David says, “The LORD is my shepherd…” so he is likening himself to a sheep.
By the second verse we can see two different things. They need a shepherd to lead them to pasture to eat. It has been said that sheep will eat grass down to the dirt, and practically kill it off, if they are not moved to green pasture. If you will read the gospel account of Jesus feeding the 5,000 men, not counting women and children (Matthew 14:15-21) you will read in verse 19 that the narrative reads, “And He commanded the multitude to sit down on the grass…”; the gospel of Mark even says “upon the green grass” (Mark 6:39) and John simply says, “Now there was much grass in the place” (John 6:10). You talk of a shepherd leading the sheep to green pastures; Jesus is the Shepherd. He gives His sheep plenty to eat, and then He gives us plenty of good clean water to drink.
The sustenance of the Lord is bountiful. It is said that sheep are afraid of moving water, so the shepherd leads them to smooth, still water; not stagnant, that would make them sick, but still, smooth, fresh, and clean water. For refreshment, and the nourishment their bodies need. If a sheep needs to cross the water the shepherd will lead them to still water for crossing as well, where it is shallow enough as to not soak up in their fleece as to load them down and drown them.
The LORD is the Lamb of God laid down His life for me. He is my Shepherd too; who leads me to green pastures and I can lie down in them comfortably, and have food for the day; then, He leads me to the right place for a refreshing drink and for the purpose of life.
The Shepherd is the Lamb. He is the Bread of Life. He is the Light of the world. Jesus Christ is the Shepherd who gives His life for the sheep. He gave His life for His sheep on the cross, was buried, and He rose again. You can trust the Shepherd to provide what you need.
