Question about Christ's Atonement

[Andrew]

Did His Atonement forgive the sins of those who died in Noah's time who heard and accepted Christ's preaching to the dead in Hades?

I know that the Bible does not offer us much detail but did He save any souls that were in Hades, even the disobedient?

 

[Josiah]

IMO,

Justification has always been the same: Sola Gratia - Solus Christus- Sola Fide. ALWAYS. It's just those before Christ had faith focused on the Messiah yet to come whereas those of us after Christ have faith focused on the Messiah who has come. Same/same.

The short answer is yes.
We are saved by grace, through faith. This has been true from the moment Adam and Eve sinned.
Jesus atoning sacrifice is past, present and future. There was no need to evangelize the dead and bring them to salvation. That is a Mormon teaching I do not agree with.
