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.
My sheep hear my voice, and I know them, and they follow me:
And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
I and my Father are one.
John 10:25-30 King James Version
