King David took great comfort and confidence in the Lord as his personal Shepherd. Because of this faith, he did not fear any future lacking, he did not fear any evil even in the valley of the shadow of death, and his cup ran over from God’s blessings. If we understand this one bedrock truth, that God is our Shepherd and will always care, provide for, and protect us as his sheep, we can like contented and live without fear here in this world, just as David the shepherd boy did.
