I am the good shepherd. A good shepherd lays down his life for the sheep.
A hired man, who is not a shepherd and whose sheep are not his own, sees a wolf coming and leaves the sheep and runs away, and the wolf catches and scatters them.
This is because he works for pay and has no concern for the sheep.
I am the good shepherd, and I know mine and mine know me, just as the Father knows me and I know the Father; and I will lay down my life for the sheep.
I have other sheep that do not belong to this fold. These also I must lead, and they will hear my voice, and there will be one flock, one shepherd.
This is why the Father loves me, because I lay down my life in order to take it up again.
No one takes it from me, but I lay it down on my own. I have power to lay it down, and power to take it up again. This command I have received from my Father."
~ JOHN 10:11-18. (NIV)
