7 Nevertheless, I tell you the truth: it is to your advantage that I go away, for if I do not go away,the Helper will not come to you. But if I go, I will send him to you.
8 And when he comes, he will convict the world concerning sin and righteousness and judgment:
9 concerning sin, because they do not believe in me;
10 concerning righteousness, because I go to the Father, and you will see me no longer;
11 concerning judgment, because the ruler of this world is judged.
12 "I still have many things to say to you, but you cannot bear them now.
13 When the Spirit of truth comes, he will guide you into all the truth, for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come.
14 He will glorify me, for he will take what is mine and declare it to you.
15 All that the Father has is mine; therefore I said that he will take what is mine and declare it to you.
One of the things I like about John is his descriptions of the Holy Spirit. Here John teaches us that the Holy Spirit will be our guide into all truth. We also know that He glorifies Jesus.
