This is what most Christians still believe but I consider it completely absurd. It has no basis in the Bible but rather it is based upon a misinterpretation of Bible verses. Dead and decomposed bodies don't come back to life again and rise from their graves. That is patently absurd. Christians say "God can do anything because God is omnipotent" but why would God do that?
No, the physical body once dead remains dead and the soul (spirit) leaves the body and ascends to the spiritual world (Heaven or Hell).
After the physical body dies the soul is raised as a spiritual body and goes to heaven where it continues to live forever.
The physical body cannot exist in the Kingdom of God in heaven. That is why it needs to be transformed into a spiritual body.
That is what the Bible actually says.
1 Corinthians 15 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!
Physical bodies will not be resurrected and then go to heaven since physical bodies cannot exist in heaven, since heaven is a spiritual world, not a physical world.
"will not perish but have everlasting life." Everlasting life (eternal life) refers to the state of the soul that is near to God, it has nothing to do with the physical body living forever. All souls will continue to exist forever since the soul is immortal, but the souls who are near to God will have everlasting life. The souls who are far from God will continue to exist, but they will be "as dead souls" since they will be spiritually dead (not near God). That is what Hell is.
Of course, this is all according to my Bahai beliefs, but I think it is supported by the Bible, when the Bible is interpreted correctly.
