Verses 13 to 16 of John 16.

When the Spirit of truth comes, he will guide you into all truth. He will not speak on his own but will tell you what he has heard. He will tell you about the future. He will bring me glory by telling you whatever he receives from me. All that belongs to the Father is mine; this is why I said, ‘The Spirit will tell you whatever he receives from me.’

“In a little while you won’t see me anymore. But a little while after that, you will see me again.”
