“It’s not a matter of having committed a sin, even one as heinous as murder,
it’s a matter of calling Evil Good and Good Evil,”
OK, I see what you are saying, but is being wrong unforgivable? Surely we do not recognize every evil. We are easily deceived and often we are too willing to be deceived to justify our actions, no? Does our salvation hinge on never tripping up in this regard?
I’m not the judge of anyone’s salvation - that’s up to the Big Guy.
However, it’s pretty biblically clear that we all understand right and wrong, as it is written in our hearts,
and that these folks are not only actively rejecting rebukes that remind them of the evil,
they are causing others to commit evil as well - KNOWINGLY, just to justify something they can’t forgive themselves for.
Again, not my place to say whether they are saved or not - but it is my place to “judge rightly” and to rebuke as lovingly as I can.
