Some of that is not Biblical. All those who have died in the flesh have already been raised literally, and live unto God as spirits.
There is only one bodily resurrection of ALL flesh from the graves. That is an hour that is coming, when the last trumpet sounds that marks time for this earth shall be no longer, this is the last day of this age when time shall be no longer.
John 5:28-29 (KJV) Marvel not at this: for
the hour is coming, in the which all that are in the graves shall hear his voice, And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
John 6:39 (KJV) And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should
raise it up again at the last day.
John 6:40 (KJV) And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and
I will raise him up at the last day.
John 6:44 (KJV) No man can come to me, except the Father which hath sent me draw him: and
I will raise him up at the last day.
John 6:54 (KJV) Whoso eateth my flesh, and drinketh my blood, hath eternal life; and
I will raise him up at the last day.
John 11:24 (KJV) Martha saith unto him,
I know that he shall rise again in the resurrection at the last day.
John 12:48 (KJV) He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken,
the same shall judge him in the last day.
Colossians 3:4 (KJV) When Christ, who is our life, shall appear, then shall ye also appear with him in glory.
1 Peter 1:5 (KJV) Who are
kept by the power of God through faith unto salvation ready to be revealed in the last time.
Romans 8:11 (KJV) But if the Spirit of him that raised up Jesus from the dead dwell in you,
he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
Philippians 3:20-21 (KJV) For our conversation is in heaven; from whence also
we look for the Saviour, the Lord Jesus Christ: Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.
Revelation 10:5-7 (KJV) And the angel which I saw stand upon the sea and upon the earth lifted up his hand to heaven, And sware by him that liveth for ever and ever, who created heaven, and the things that therein are, and the earth, and the things that therein are, and the sea, and the things which are therein, that
there should be time no longer: But
in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.
The physically dead in Christ, just as John tells us, are living souls in heaven having eternal spiritual life they are a spiritual body of Christ in heaven just as they had been in life.
That's who those "spirits in prison" of 1 Peter 3 are, and in 1 Peter 4 Peter said they live unto God now, meaning literally in the heavenly dimension.
This passage shows us those disobedient people living in the days of Noah through the same Spirit that raised Christ from the dead preached through His servant Noah to them. Their spirits have gone into prison/grave to be reserved for Judgment because in life they did not heed the words of God spoken through righteous Noah. Though God was patiently waiting while Noah prepared the ark, these
all remained in disobedience with the exception of eight souls that were saved from the flood waters that came upon the whole earth.
1 Peter 3:18-20 (KJV) 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: By which also he went and preached unto the spirits in prison; Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water.
The gospel is not preached to the physically dead. What purpose would be served since the spirit that gives man physical life has departed from the dead? We preach the gospel of the Kingdom of God to the spiritually dead, those who Paul tells us are dead in trespasses and sins. Not physically dead of course, but spiritually dead, in which we all are before we become saved. Mankind dies once, and if in unbelief, next comes the Judgment Day for them.
1 Peter 4:5-6 (KJV) Who shall give account to him that is ready to judge the quick and the dead. 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 'dead in the ground' theory is an old primitive Jewish doctrine that treats one's spirit and soul as if it were made up of fleshy material matter along with the flesh body.
When we die our body, not our spirit, returns to dust from which it came. The breath of life (spirit) goes out of man, and the body returns to dust. The body returns to dust, and the spirit returns to God who gave it. The question we must all ask is will our spirit return to God with the breath of life through the Spirit of Christ in us, or will our spirit return to God in silence and darkness in unbelief?
Genesis 3:19 (KJV) In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou
art, and unto dust shalt thou return.
Psalm 104:29 (KJV) Thou hidest thy face, they are troubled: thou takest away their breath, they die, and return to their dust.
Ecclesiastes 12:7 (KJV) Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
No, you've got it backwards. Our flesh is not what is saved by Christ. It is our spirit with soul that is saved. There is no salvation of the flesh.
When we possess eternal spiritual life through the Spirit of Christ in us, our spirit will NEVER die. Our spirit alive shall return with Christ' return to give life to our resurrected immortal and incorruptible body of flesh. Christ saves the whole man, not in part but the whole. If this were not truth it makes ZERO sense for the Bible to say in an hour coming all that are in the graves (dead bodies) shall be resurrected either for life or condemnation. In the same way that God made the body of flesh from dust is the same way our decomposed bodies shall be resurrected to physical life again. And in the same way that lump of clay had life breathed into it by the breath of God, so too our living eternal shall give physical life to our resurrected immortal body that man of faith shall once again be whole.
