John 10:11 - I am the good shepherd. The good shepherd lays down his life for the sheep.
In the ancient Near East, the gods were too remote to be called "shepherd". Kings were given that title. In the Old Testament, "The Lord is my shepherd", God is the Shepherd of Israel . In Ezekiel, God promises that He will come down to Israel to be their true shepherd. Thus Jesus claims to be the Lord and God of the Old Testament. But the Good Shepherd is also the Lamb of God who takes away the sins of the world.
Amazing love, how can it be that thou my God should die for me.
