The Holy Spirit will not tell you or anyone else something that cannot be verified by Scripture? Firstly, where's that statement verified in Scripture? Secondly, that statement goes against what you said I'm right about, which is that God speaks whenever, wherever, to whomever and about whatever He wills. Thirdly, say the Father, the Son, or the Holy Spirit revealed to you, for example, in-depth details surrounding the creation of the angels, the rebellion of Lucifer and other angels, the creation of the universe, as well as the disobedience of Adam and Eve. Or, how about Jesus's discourses in full, not the summarizations of them in Scripture. The list can go on. All details that aren't found in any of the scriptural books. How would you verify those details using the scriptural books? You get around that by saying the following:
"He will tell you the future of what will happen, and it will happen. But not embellish past history."
Where's that statement verified in Scripture?
