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 certainly not cast out.

No one can come to Me unless the Father who sent Me draws him; and I will raise him up on the last day. It is written in the prophets, ‘AND THEY SHALL ALL BE TAUGHT OF GOD.’ Everyone who has heard and learned from the Father, comes to Me.

And He was saying, “For this reason I have said to you, that no one can come to Me unless it has been granted him from the Father.”
