John 6:37-39

³⁷All those whom the Father gives me will come to me; and no one who comes to me will I ever turn away.

³⁸For I have come down from heaven, to do, not my own will, but the will of him who sent me;

³⁹and his will is this — that I should not lose one of all those whom he has given me, but should raise them up at the Last day.
