John 16:7, 12-13

But I tell you the truth, it is better for you that I go away. When I go away, I will send the Helper to you. If I do not go away, the Helper will not come.

“I have many more things to say to you, but they are too much for you now. But when the Spirit of truth comes, he will lead you into all truth. He will not speak his own words, but he will speak only what he hears, and he will tell you what is to come.
