Psalm 23 and John 10 are the most beautiful descriptions of God as our Shepherd, Jehovah Rohi. When we say "Lord," we think of God's deity. When we say "my Shepherd," we think of God's humanity. God in human form - Jesus Christ - prophesied in the Old Testament and revealed in the New Testament. The Jehovah of the Old Testament is the Jesus of the New Testament. As the Good Shepherd, He dealt with the penalty of sin. As the Great Shepherd, He deals with the power of sin. As the Chief Shepherd, He's coming to take us from the very presence of sin.
