Thematic Bible: Knows each one of his flock by name

It's to him the gatekeeper opens the gate, and it's his voice the sheep hear. He calls his own sheep by name and leads them out. When he has driven out all his own, he goes ahead of them, and the sheep follow him because they recognize his voice. They'll never follow a stranger, but will run away from him because they don't recognize the voice of strangers."
