Do you have the verse(s) citing that Jesus was in Hades? The KJV does not list it as Hades, but I can agree that His body was in the grave, but the term is defined by how it is used in the verse in according to the message given as it can also refer to the afterlife.
Not really. All thoughts for the land of the living is done because they are no longer in the land of the living to be thinking about it. They do have thoughts though, but not about anything in the land of the living.
It is literal depending on how the KJV has it.
As for the afterlife, we have this sin of King Saul consulting a witch to bring up the spirit of Samuel, the prophet.
1 Samuel 28th Chapter
No one can say that was not the prophet Samuel when he had prophesied King Saul's and his son's death in the field of battle and it came true.
God forbids saints to consult with mediums and such not because they cannot contact the dead, but they were to go to the Lord for guidance and answers.
Isaiah 8:19 And when they shall say unto you, Seek unto them that have familiar spirits, and unto wizards that peep, and that mutter: should not a people seek unto their God? for the living to the dead?
And so for Him to descend to preach unto them in prison, ( Abraham's bosom aka Paradise ) He has to be conscious as well as those He has preached to for them to hear the Good News,
Ephesians 4:8 Wherefore he saith, When he ascended up on high, he led captivity captive, and gave gifts unto men. 9 (Now that he ascended, what is it but that he also descended first into the lower parts of the earth? 10 He that descended is the same also that ascended up far above all heavens, that he might fill all things.)
1 Peter 3:18 For Christ also hath once suffered for sins, the just for the unjust,
that he might bring us to God, being put to death in the flesh, but quickened by the Spirit: 19 By which also he went and preached unto the spirits in prison;
Plus He did say to the thief on the cross....that he would meet Him that day after death.
Luke 23:42 And he said unto Jesus, Lord, remember me when thou comest into thy kingdom. 43 And Jesus said unto him, Verily I say unto thee, Today shalt thou be with me in paradise.
So Abraham's bosom aka Paradise, was originally located beneath the earth but across that great gulf from hell but since His resurrection and ascension, He has brough the captivity captive by bringing Paradise to Heaven in leading the way as only He can bring us to God the Father in Heaven. Paul testified of the apostle John ( indirectly ) in having been taken to Paradise in the third Heaven for writing the Book of Revelation.
2 Corinthians 12:1It is not expedient for me doubtless to glory. I will come to visions and revelations of the Lord. 2 I knew a man in Christ above fourteen years ago, (whether in the body, I cannot tell; or whether out of the body, I cannot tell: God knoweth
such an one caught up to the third heaven. 3 And I knew such a man, (whether in the body, or out of the body, I cannot tell: God knoweth
4 How that he was caught up into paradise, and heard unspeakable words, which it is not lawful for a man to utter.
Proof that Paradise was not in Heaven before Christ's death, resurrection & ascension
John 3:13
And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
Only Christ can bring us to God the Father and so there is no other way than by the blood of the Lamb of God.
Granted, Enoch and Elijah were taken up to the heavens, but not the third heaven which is God's throne. I suspect that they are travelling through time and space to be dropped off after the pre great tribulation rapture to serve as the 2 witnesses in Jerusalem for the first half of the great tribulation for when they will die, and be resurrected and called to come up hither halfway through that great tribulation.
Revelation 11:1-13 KJV
There is precedent for this kind of divine transportation as the apostle Philip was transported from one place to another.
Acts 8:37 And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God. 38 And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him. 39 And when they were come up out of the water,
the Spirit of the Lord caught away Philip, that the eunuch saw him no more: and he went on his way rejoicing. 40 But Philip was found at Azotus: and passing through he preached in all the cities, till he came to Caesarea.
May God cause the increase as I know I cannot do that.
