John 10:26

24 Then came the Jews round about him, and said unto him, How long dost thou make us to doubt? If thou be the Christ, tell us plainly.

25 Jesus answered them, I told you, and ye believed not: the works that I do in my Father’s name, they bear witness of me.

But ye believe not, because ye are not of my sheep, as I said unto you.

27 My sheep hear my voice, and I know them, and they follow me:

28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.

Do read the surrounding verses too, because the context often says more than a single verse.
