Thanks, Virgil, for clarifying. The “premillennial dispensationalists” I used to hang around with also believed in sola Scriptura during the present age, though of course theirs was a different eschatology from yours. The closing of revelation does, as you point out, resolve the issue of distinguishing the true prophets from the false. What remains, then, is discerning truth from error in Scriptural interpretation. If you believe that the Bible is self-interpreting, then even that problem goes away.

Samuel (or is it Sam L.?), it seems to me also that, when the perfect comes, God would open a clearer and wider channel of communication than Bible reading — or even Spirit-inspired theologizing.
