It actually does, I don’t know how you don’t see it. That’s up to you though to read and let the Holy Spirit do his work.
Would be great if you could point it out...I am aware of the “Scripture is useful” line which falls well short of saying it is all you need to know the truth; (useful as a hammer is to carpentry; try being a carpenter with just a hammer) And as for me reading the Bible and letting the Holy Spirit do his work, I would never know if it is the HS or Satan, which would explain how the supposed HS has guided the creation of bunches of contradictory denominations, all founded by people claiming it was guided by the HS.
