The thief comes only to steal and kill and destroy.
He has always been a murderer and a liar. There is nothing truthful about him. He speaks on his own, and everything he says is a lie. Not only is he a liar himself, but he is also the father of all lies.
I have come in order that you might have life--life in all its fullness.
My sheep listen to my voice; I know them, and they follow me. I give them eternal life, so that they will never be lost.
