No scripture, just commentary, commenters nearly all disagree it's meaning!
1 Peter 4:6 For for this cause was the gospel preached also to them that are dead, that they might be judged according to men in the flesh, but live according to God in the spirit.
The most of them say "Those who are 'spiritually dead' not literally dead, but a few opt for the actual dead.
All my life I have heard this topic discussed and comments like Jesus went down into hell and preached the gospel to the lost souls imprisioned there. When I read the bible for myself, 'lo and behold' nada, zip, zilch, not once in simple easy to understand scripture or verse that said that!
Again, 'the precepts of men'! choose your poison! Your 'EarCandy!'
I'll just keep on with what is written and can be proven in the Tanack! Too much tampering with the NT! You must 'prove all things written in it.'
Shalom
