John 16:12-13

12I have many more things to tell you. But you are not strong enough to know them now.

13But the Spirit will come. He is the one who shows people true things about God. When he comes, he will be a guide to you. He will help you to understand everything that is true. He will not speak on his own authority. He will tell you only what he hears from the Father. He will tell you about things that will happen after this time.
