You impugn your own argument with this recourse, since freedom in areas of personal liberty is not the same as doctrine.
And when Christ warns of everlasting punishment in the same lake of fire that the devil will forever be tormented in forever, (Mt. 25:41,46; Rv. 20:10) of flaming fire taking vengeance on Christ-rejectors, of everlasting destruction, (2 Thessalonians 1:8," and of "weeping," "wailing" and "gnashing of teeth,"(Mt. 8:12; 13:42,50; 22:13; 24:51; 25:30) of "unquenchable fire," that is so real that one should ruthlessly cut out of their life whatever actually leads us to sin, (Mark 9:43-48) then we are not dealing with freedom to eat pork, but a basic doctrine of dire consequences for forfeiting one's day of grace.
OK, using my “litmus test”, is Jesus going to say to you or me, at the GWTJ, “Sorry, you had that hell thing wrong. You are not saved.”
My take is, no. So it falls under 2 Timothy 2.
Regarding that lake of fire stuff, I’ve argued this as much as is necessary in the past. I know what I believe and I know what I teach my students. And I can back it up.
The “Goldilocks” argument, for me, is Jewishnotgreek.net. That is, it’s not exhaustive, and it’s not overly simplistic. It covers all the bases enough for most people.
