John 6:37, 44-45, 65

All that the Father gives Me will come to Me, and the one who comes to Me I will by no means cast out.

No one can come to Me unless the Father who sent Me draws him; and I will raise him up at the last day. It is written in the prophets, ‘And they shall all be taught by God.’ Therefore everyone who has heard and learned from the Father comes to Me.

And He said, “Therefore I have said to you that no one can come to Me unless it has been granted to him by My Father.”
