The words of Christ, guaranteeing those whom he truly saves that they do and will have eternal life, can never be lost, and therefore will also be raised:
"For I have come down from heaven, not to do my own will but the will of him who sent me. And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day. For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.” John 6:38-40
