No difference here. Please don't tell me that you understand Tota Scriptura to mean, straight from a Bible, verbatim.
I'm simply saying that if I walk up to a Muslim and attempt to tell him that Muhammed is not a prophet, and that only Jesus is the Alpha and the Omega. Or, go to a Jew and tell them that the Levitical Law is not binding anymore, in regard to one's salvation with God.
First, I ask you, have I spoken the God-given truth, and two, if so, why, ....because the Scriptures say so, and only so.
In other words, I can't tell a Buddhist or Hindu that they're saved, because that does not conform to Scripture.
No one is denying the invariable conflict and controversy that will arise, whenever interpretation is involved. I imagine that God planned it this way, in that it reveals a great deal about one's heart as to what they believe. Everything is subjective, even one's claim of hearing the Spirit talk, as opposed to their own imagination or devil spirits.
God has left us with a dilemma, in regard to the obligation to study and pray in order to extrapolate the truth from His revelation. Even the spirits we must question and test. Nothing is unequivocal.
