Verses 23 to 28 of John 16.

At that time you won’t need to ask me for anything. I tell you the truth, you will ask the Father directly, and he will grant your request because you use my name. You haven’t done this before. Ask, using my name, and you will receive, and you will have abundant joy.

“I have spoken of these matters in figures of speech, but soon I will stop speaking figuratively and will tell you plainly all about the Father. Then you will ask in my name. I’m not saying I will ask the Father on your behalf, for the Father himself loves you dearly because you love me and believe that I came from God. Yes, I came from the Father into the world, and now I will leave the world and return to the Father.”
