Alright, so where did Jesus preach to the dead? Where did he go to do that? The truth in the parable says that one side was Abraham's bosom and one side was place of torment, there was a gulf between them that nobody could cross. It was considered the underworld. Hell in OT is shehole: hades or the world of the dead (as if a subterranean retreat) includ. its accessories and inmates_grave, hell, pit. In the NT in Greek, one is Geenna: valley of (the son of) Hinnom; gehenna (or Ge-hinnom), a valley of Jerus, use (fig) as a name for the place (or state) of everlasting punishment:_hell. The second one is hades: place of departed souls:_grave, hell.
Also in Psalm 86:13 talking about Jesus....Great has been your kindness me; you have rescued me from the depths of the nether world (hell). Using a Catholic bible here on this one. Also Psalm 139: 8.....If I go up to the heavens, you are there; if I sink to the nether world (hell), you are present there. Again Catholic bible. Now, you don't believe God is in the torment side of hell, do you? What part of hell is he in? Paradise of course. Whether it's Jesus preaching to the OT believers in paradise those 3 days, or God of all time, he's in paradise. Also if hell didn't have 2 sides, again I ask, why does the creed you recite every week use the word hell? As far as agreeing that there's is another place beside hell and heaven, sort of I guess but actually no because paradise is part of hell, in the OT. Now, paradise has been emptied (by Jesus) and now hell is all torment. Let me give you an earthly example. I live in central Fl, and sometimes we go to Disney World. Well Disney World consists of 4 theme parks (not counting water parks, and entertainment places, etc), Magic Kingdom, Epcot, Hollywood Studios, Animal Kingdom. Now, it's all called Disney World. If I go to Disney World, I may only go to Magic Kingdom. I may truthfully tell someone, Oh I went to Disney World today, or I just may say, I went to the Magic Kingdom today. Now if I tell someone who doesn't live here that I went to Disney World today, most likely they will automatically think the Magic Kingdom, and let it go from there. Most non-locals think Magic Kingdom is Disney World, no, it's a part of Disney World not exclusively DW. If I say to someone who lives here the same, they will ask me, Which park did you go to?. Then I will say Magic Kingdom. Well, thirty years ago though, if I said I went to DW then yes, it would've been exclusively Magic Kingdom. That was the only park they had here in Fl at that time. So think of the bible in reverse in this story, OT had hell (Disney World), which consisted of 2 places, torment and paradise (Magic Kingdom and Epcot, 2nd park), so if someone went to hell before the resurrection, it would've been 1 of 2 places. Now in the NT, hell (Disney World pre- 1988) is 1 place (Magic Kingdom)only. I hope this doesn't confuse you, but I don't know how else to explain it.
