John 6:37

6:37 Everyone whom the Father gives me will come to me, and the one who comes to me I will never send away.

John 6:39-40

6:39 Now this is the will of the one who sent me – that I should not lose one person of every one he has given me, but raise them all up at the last day. 6:40 For this is the will of my Father – for everyone who looks on the Son and believes in him to have eternal life, and I will raise him up at the last day.”
