Paul doesn’t believe in the physical rising of the dead, I’ll elucidate myself, since I don’t think anyone is understanding my point.
It is the same with the dead who are raised to life. The body that is “planted” will ruin and decay, but it is raised to a life that cannot be destroyed.
When the body is “planted,” it is without honor, but it is raised in glory. When the body is “planted,” it is weak, but when it is raised, it is powerful.
The body that is “planted” is a physical body. When it is raised, it is a spiritual body. There is a physical body, and there is also a spiritual body. (1 Corinthians 15:42-44)
Here Paul is saying that the body that is ‘planted’ (i.e. our physical bodies) will ruin and decay after we die, but the body in which we are raised back to life in will be glorified and free from damage. The former is our physical body, the later is our spiritual body, it is the spiritual body which Paul says will be raised, not the physical, which will rot away.
Now why does Paul believe this, well as he continues he links this with his doctrine of Jesus dying to save us from our sin:
*It is written in the Scriptures: “The first man, Adam, became a living person.” **But the last Adam became a life-giving spirit. **
The spiritual did not come first, but the physical and then the spiritual.
The first man came from the dust of the earth. **The second man came from heaven. *People who belong to the earth are like the first man of earth. But those people who belong to heaven are like the man of heaven.
Just as we were made like the man of earth, so we will also be made like the man of heaven. (1 Corinthians 15:45-49)
And he says something related to this earlier on in the letter:
In Adam all of us die. In the same way, in Christ all of us will be made alive again.
But everyone will be raised to life in the right order. Christ was first to be raised. When Christ comes again, those who belong to him will be raised to life (1 Corinthians 15:22-23)
So, what Paul is teaching here is that Christ came to sacrifice himself in order to save us from sin, that’s standard Christianity of course. But how he says Christ did this is that he was the last Adam, here to right the wrongs of the first Adam. The first Adam came from the dust of the Earth, that is he was born into a physical body and died in a physical body, but he contrasts this with the ‘last Adam’ as being a man of Heaven, who came in a physical body, but rose again in a **spiritual **body. He says that Jesus became a 'life-giving spirit’, and the people who believe in him will be made like the man of heaven from being a man of the Earth like Jesus was, we will be risen again as spirits, free from our weak physical bodies, like Jesus was freed from his.
Now why is escaping our physical bodies so important to Paul? Well continuing on:
*I tell you this, brothers and sisters: Flesh and blood cannot inherit the kingdom of God. Something that will ruin cannot have a part in something that never ruins.
But look! I tell you this secret: We will not all sleep in death, **but we will all be changed.**It will take only a second—as quickly as an eye blinks—when the last trumpet sounds. The trumpet will sound, and those who have died will be raised to live forever, and we will all be changed.
**This body that can be destroyed must clothe itself with something that can never be destroyed. *And this body that dies must clothe itself with something that can never die.
So this body that can be destroyed will clothe itself with that which can never be destroyed, and this body that dies will clothe itself with that which can never die. When this happens, this Scripture will be made true:
“Death is destroyed forever in victory.” — Isaiah 25:8
“Death, where is your victory?
Death, where is your pain?” — Hosea 13:14
Death’s power to hurt is sin, and the power of sin is the law. But we thank God! He gives us the victory through our Lord Jesus Christ. (1 Corinthians 15:50-57)
The first couple of lines really say all that’s necessary. Paul believes that people die with their physical bodies, and that flesh and blood (i.e. physical bodies) cannot inherit the Kingdom of God. So mankind is doomed, but the good news is Jesus came to save us from our physical bodies by laying down his life for us and then being the first man to rise again from the dead as a life-giving spirit, escaping death, and allowing those who believe in him to rise again in the same manner, escaping their physical bodies. We die in our physical bodies like Adam, and rise again as spirits like Jesus did. In Paul’s doctrine, flesh and blood means sin and death, and the spirit is life. Jesus rising from the dead as a spirit is him defeating sin and death, because it’s the spirit that cannot be destroyed.
For Paul, if Jesus rose from the dead in his physical body then that would mean he hadn’t defeated sin and death, as that’s what the physical body is, and that’s what Jesus was escaping in the first place. His sacrifice would have been pointless.
