What is this part of the bible about John 16:12-13 ESV

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.

it is sayin that: what he has to say to you know that it is not time for you to hear them.

when a"spirit" (angle) comes to you 'children of god' saved or not, he will explain

and we will be forward for the thing that are about to come.

good question to ask your self "has it already happen"

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.
