It is not for us to judge them because we have no Heaven or Hell to place folks. Only ABBA knows their hearts,my and yours.
I don't judge them, but there is a big difference in judging somebody and then doing as Paul said and that is to reprove, rebuke, and then exhort somebody with the scriptures as he said in 2 Timothy 3:16. Reprove means to reprimand one when they are in the wrong, rebuke then is show them by scripture the right way, and then exhort them is to encourage them to look into that proper context on how to use it or apply to their life. So we are called to point out where they have been led astray by a false teaching. And the bible also speaks of those who think they are wise and fully educated in the word and think they are never wrong, as prideful and will be made to look foolish.
I myself have gained more insight while being on this site on some subjects of the bible, thanks to God working by the Holy Spirit through individuals. But I have also seen some that claim to be highly educated and correct in the word, using unedifying and unloving words toward others who disagree with them. This shows their fruit they produce by being that way, and if I see such a one using such unedifying and unloving tactics then by what the bible says; It says not to listen to them, and not even eat with such a person named a brother that continues to live in and not give up those sinful ways. As anything not done in a edifying or loving way is sin......
