The Holy Spirit will be your guide into all true knowledge

The Holy Spirit, your helper

However, when he, the Spirit of true knowledge, has come, he will be your guide into all true knowledge: for his words will not come from himself, but whatever has come to his hearing, that he will say: and he will make clear to you the things to come.
John 16:13

Joh 16:7 But what I am saying is true: my going is for your good: for if I do not go away, the Helper will not come to you; but if I go, I will send him to you.

Joh 16:8 And he, when he comes, will make the world conscious of sin, and of righteousness, and of being judged:

Joh 16:9 Of sin, because they have not faith in me;

Joh 16:10 Of righteousness, because I go to the Father and you will see me no more;

Joh 16:11 Of being judged, because the ruler of this world has been judged.

Joh 16:12 I have still much to say to you, but you are not strong enough for it now.

Joh 16:13 However, when he, the Spirit of true knowledge, has come, he will be your guide into all true knowledge: for his words will not come from himself, but whatever has come to his hearing, that he will say: and he will make clear to you the things to come.
