It seems to ME that a person who thinks that one has a body at all at the Pearly Gates is already beyond the ability to engage in reason.
Let me put it this way. The sanctuary of God, his dwelling place, is a realm of conscious existence defined by the boundaries of thought and behavior defined in the law. To enter this kingdom of God, heaven, the world above, the realm of eternal life, one must conform to the laws demands.
When Jesus called on his people to repent or they would never enter the kingdom of heaven he was talking about them repenting and entering the kingdom of heaven while they still had a body. If a person hears and acts on the teaching of Jesus about how to correctly understand and apply the law according to his revelation about the deeper hidden meaning behind the words and subjects they will attain the highest aim in life, comprehension and communion with God, which is eternal life. If not and they instead hear what Jesus taught and discount it they cannot enter that realm while they have a body and become subject to the judgment according to their words and deeds when their body dies.
Some people are accepted and some people are banned from the kingdom of heaven
whether they have a body or not.
The world above vs the world below is not about any dimensional difference of some mystical places of existence it is simply about the conscious world of higher intelligences vs the conscious world of low lifes which all are in existence simultaneously on earth.
I will tell you something. Try to hear.
There is a gulf which separates the two worlds that is as great as the gulf which separates the living from the dead.
Rise to life and enter the kingdom of God while you have a body to ascend in. both literally and figuratively, no one can repent from the grave.
