John 6:37,39.   All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. ...And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. John 10:15-16,27-28.   As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep. And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd. ...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.
