That Jesus is the good Shepherd of His sheep gives Him a beautiful identity. It identifies Christ as our great divine Pastor and Savior. A shepherd is a pastor. We are familiar with the fact that God has given us pastors in the church on earth. They are undershepherds to lead us into the green pastures of God's Word by their preaching, by their love for us, and by their care for our souls, and to serve as our guides to heaven.
True pastors are a great blessing to the church.
But we must know that when Jesus says here that He is the good Shepherd, He is identifying Himself to us as the Shepherd of all shepherds, the true Pastor of the church. All the ministers of the church really serve under Christ and reflect His office as pastor. All God's people are really pastored by the good Shepherd, Jesus Christ. That is what Jesus is as the Shepherd of His people. Jesus is the Shepherd of the sheep.
