Are there any books other than OT and NT that give any details on the WORD or what's on his mind? Or, must we rely on personal revelation, as given by God via the Holy Spirit?
It's not a case of either/or you know, you're not part of the WT anymore, you can decide for yourself :)
It is a case of both, while the NT is a collection of writings from the first couple of generations Christians, inclduing the apostles, it is NOT meant to replace or hold more "infulence" than the guiding force of the HS.
