I’m sorry for repeating myself here, but there’s simply no way unbelievers could be righteous when in at least two verses the NT explicitly says all unbelievers are condemned. What is your interpretation of the following?
Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.
16 Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.
Correct me if I’m wrong, but you seem to think that the only unbelievers who can be righteous are unbelievers who have never heard the gospel. Why exactly someone who heard the gospel but didn’t believe would be condemned is not clear at all. It would imply that a person becomes guilty of something when they discover the gospel, and that they can only become righteous now by believing. But what then are they guilty of and what then is the gospel?
