So you think God made a mistake when He inspired "bringing on themselves swift destruction" in the context of "for whom the blackness of darkness has been reserved forever"?
Why are you adding to the scriptures?
2 Peter 2:1 And there did come also false prophets among the people, as also among you there shall be false teachers, who shall bring in besides destructive sects, and the Master who bought them denying, bringing to themselves quick destruction,
First it is speaking about false prophets and then false teachers.
Second, it is speaking of one of those false doctrines which does bring "destructive teaching."
That which brings "the false teachers to quick destruction" would be the whole of what they taught, not the one example that Peter gave.
I do not believe that you are either a "false teacher or false prophet" in the sense that Peter is using the word. Nor do I believe that you are headed to swift destruction. But I do believe that the doctrine Peter gives is a destructive teaching. I believe that it is quite apparent in that verse and cannot be denied.
