John 16:13 were the words spoken to the disciples of Jesus for a specific time and purpose. They are not written
to us. That is not to say they are not written for us nor is it to say that the HS won't guide us into any truth. As one commentator puts it"
This does not answer the question, however, whether these words are addressed to all followers of Jesus, or only to his apostles. Since the in the context of the Last Discourse Jesus is preparing the Twelve to carry on his ministry after his departure, it seems best to take these statements as specifically related only to the Twelve. Some of this the Holy Spirit does directly for all believers today; other parts of this statement are fulfilled through the apostles (e.g., in the giving of the Book of Revelation the Spirit speaks through the apostles to the Church today of things to come). One of the implications of this is that a doctrine does not have to be traced back to an explicit teaching of Jesus to be authentic; all that is required is apostolic authority.
This reminds me of STR.org who pushes the idea of "never reading a Bible verse." Why? Because context matters. Who is the audience? Who are the recipients of those words? Who is speaking and to whom are the words intended?
This verse, John 16:13, is often used as a proof text that the HS guides us into all truth. But it's not true that we have all truth so it can't mean that. It can't be true that we'll be guided into all truth while at the same time seeing through a glass dimly.
It's like those who hold to Jermiah 29:11 "For I know the plans I have for you,” declares the Lord, “plans to prosper you and not to harm you, plans to give you hope and a future."
People claim this verse as if it was written to them. Well, does God know His plans for you? Yes. But this verse is NOT written to any of us as a promise any more than is Jeremiah 44:11 is for you:
“Therefore this is what the Lord Almighty, the God of Israel, says: I am determined to bring disaster on you and to destroy all Judah.
Yes the HS guides us into truth but not all (that can be known). And we ought to be very careful in assuming that we've heard from the HS just because we think so. The person you should least trust when it comes to understanding the biblical message is yourself.
How can you possibly "know" when you know something? How can you possibly know with certainty that what you think you know and believe is either true of false? Before you answer, remember there are at least 4 views on the nature of Hell. This all coming from Spirit filled men! How about eternal security? We don't agree on that either. How about the place of baptism in the life of the believer? Nope, that too is controversial. This list could go on and on. It's therefore arrogant to think you personally "know" anything over and above the "knowing" of other believers. You only believe things strongly (and with reason). But so do others who think differently.
When someone says, "The HS revealed this to me......" run for your lives!
