All the Truth

When jesus says the spirit of truth will come and guide you into all the truth, is he specifically talking about the disciples there? Or is he talking about everyone who's coming later. I want to put a ze on the end of it. All the truths. Generation z millennial. Like yhou'll hear it as not only to the disciples, but also to us. But when jesus is actually speaking the words, he's going to be referencing the disciples.
