John 16:4 (WEB) - 4 But I have told you these things, so that when the time comes, you may remember that I told you about them. I didn’t tell you these things from the beginning, because I was with you.
7 Nevertheless I tell you the truth: It is to your advantage that I go away, for if I don’t go away, the Counselor won’t come to you. But if I go, I will send him to you.
13 However when he, the Spirit of truth, has come, he will guide you into all truth, for he will not speak from himself; but whatever he hears, he will speak. He will declare to you things that are coming.
