In a recent discussion on another forum, I presented the argument that the conjunction "for" (gar) in Mark 9:49 must be understood as a contrasting conjunction. While its normal function isn't that of contrast, this case seems to be an exception.
For everyone will be salted with fire. πᾶς γὰρ πυρὶ ἁλισθήσεται
My position is this. The contrast is the fires of hell verses the fire of discipline.
Would like some feed back on this ...
