What are some characteristics of Christ as the Good Shepherd?

Jesus is called the good sheperd as sorta a metaphor God is the shepard and christians are his sheep. The devil would be the theif or wolf or lion that tries to steal the lamb away. The feild in which the sheep dwell in portrais heaven and the gate to the feild is Jesus. All must get to God/The shepherd through the son/Jesus/The gate. Hope that helps.
