Physical death is unavoidable because God created us to me mortal.
Even if we stopped sinning we would still die physically. We die because we are mortal.
Nobody can resurrect dead bodies after they are dead and there is no reason to because we won't need physical bodies in heaven.
When we die our physical bodies will die and we will be raised as spiritual bodies. Paul says that our physical bodies cannot inherit the Kingdom of God and that means they cannot exist in heaven. When Paul says these dying bodies cannot inherit what will last forever, he is referring to the spiritual world (heaven), which will last forever.
1 Corinthians 15:40-54 New Living Translation
40 There are also bodies in the heavens and bodies on the earth. The glory of the heavenly bodies is different from the glory of the earthly bodies.
44 They are buried as natural human bodies, but they will be raised as spiritual bodies. For just as there are natural bodies, there are also spiritual bodies.
50 What I am saying, dear brothers and sisters, is that our physical bodies cannot inherit the Kingdom of God. These dying bodies cannot inherit what will last forever.
51 But let me reveal to you a wonderful secret. We will not all die, but we will all be transformed!
54 Then, when our dying bodies have been transformed into bodies that will never die,[c] this Scripture will be fulfilled: “Death is swallowed up in victory.[]...............
Thank you for your reply. Yes, there are both heavenly bodies and earthly bodies.
1st Corinthians is written to or addressed to Jesus' spiritual ' brothers ' ( verse one) - Matthew 25:40.
* In verse 40 Paul reasons that even animals come in many different body types besides heavenly angels with flesh-and-blood humans, and there is also inanimate creation aka *stars* so God gives appropriate bodies.
* In verse 44 then there is No immaterial soul separate or distinct from the body.
Soul dies (Ezekiel 18:4,20) when the body dies.
Just as Christ poured out his soul to death. At death dead Jesus was in the grave Acts of the Apostles 2:27.
Jesus was put to death in the flesh, but made alive in the spirit ( spirit body )- 1 Peter 3:18
There was No joining of any soul with his body, but ALL posses either a heavenly or earthly body.
One or the other, Not both, so a person who has died would have to have a body.
That would be either become a 'physical body' or a 'spirit body' as Jesus now has.
* In verse 50 we need to know how the dead are to be raised.
As with a plant the sown seed must die. Thus similar to the resurrection. Resurrection to Heaven or on Earth.
So, those called to Heaven (Revelation 20:6) are sown in a physical or fleshly body, but raised up in a spirit body.
This is because: 'Flesh' (physical) can Not inherit the kingdom.
Now, however Not all 'brothers ' called to heaven 'sleep' in death (spend time in death) but are quickly resurrected.
Raised up incorruptible ( changed from the physical to the spirit body ) - verses 50-52.
It is those who have that first or earlier resurrection ( Revelation 20:6; Revelation 2:10; Revelation 5:9-10 ) who
have that ' twinkling of an eye' resurrection to Heaven to reign with Christ for a thousand years.
They are the ones who are transformed to a spirit body.
* In verse 54 those transformed ones have resurrected spirit bodies ( verses 42-54)
So, there is a difference between Jesus' [brothers] - Matthew 25:40 - and the 'sheep' of verse 37.
The ' sheep ' who die before the thousand-year reign of Christ over Earth will have a fleshly physical resurrection.
