John 10: 22 - 30
22 It was the feast of the Dedication at Jerusalem;
23 it was winter, and Jesus was walking in the temple, in the portico of Solomon.
24 So the Jews gathered round him and said to him, "How long will you keep us in suspense? If you are the Christ, tell us plainly."
25 Jesus answered them, "I told you, and you do not believe. The works that I do in my Father's name, they bear witness to me;
26 but you do not believe, because you do not belong to my sheep.
27 My sheep hear my voice, and I know them, and they follow me;
28 and I give them eternal life, and they shall never perish, and no one shall snatch them out of my hand.
29 My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father's hand.
30 I and the Father are one."
