John 6:36-39

But as I told you before, you have seen me and still don’t believe. The Father gives me the people who are mine. Every one of them will come to me, and I will always accept them. I came down from heaven to do what God wants me to do, not what I want to do. Here is what the One who sent me wants me to do: I must not lose even one whom God gave me, but I must raise them all on the last day.
