John 6:37, 44-45, 65

However, those the Father has given me will come to me, and I will never reject them.

For no one can come to me unless the Father who sent me draws them to me, and at the last day I will raise them up. As it is written in the Scriptures, ‘They will all be taught by God.’ Everyone who listens to the Father and learns from him comes to me.

Then he said, “That is why I said that people can’t come to me unless the Father gives them to me.”
