John 6:63

61 Aware that His disciples were grumbling about this teaching, Jesus asked them, “Does this offend you?

62 Then what will happen if you see the Son of Man ascend to where He was before?

The Spirit gives life; the flesh profits nothing. The words I have spoken to you are spirit and they are life.

64 However, there are some of you who do not believe.” (For Jesus had known from the beginning which of them did not believe and who would betray Him.)

65 Then Jesus said, “This is why I told you that no one can come to Me unless the Father has granted it to him.”

Do read the surrounding verses too, because the context often says more than a single verse.
