Very good catch on the context of all of this. I'd never realized that until you pointed it out in the way that you did!
Now if I'd just been reading that gospel, chronologically through those chapters, I never would have picked out that particular verse and said - "Wow, look you can lose your salvation!"
To come to that conclusion, took someone some real hard twisting of the Scripture!
Wow - just wow!
I also noticed that you picked up that Judas is the "son of perdition". I picked that up in the Scriptures many years ago. I'm still working on how that fits in with certain other things related to the 1st century.
I'd be interested to hear your take on that as related to 2 Thessalonians 2:3. I've studied that through a bit and I know they are connected. I just haven't quite figured out how?
