John 6:29, 39-40

Jesus told them, “This is the only work God wants from you: Believe in the one he has sent.”

And this is the will of God, that I should not lose even one of all those he has given me, but that I should raise them up at the last day. For it is my Father’s will that all who see his Son and believe in him should have eternal life. I will raise them up at the last day.”
