How so? Where is that suggested in the Bible?
Revelations describes us *looking* into open heaven, and passing to a new earth, with new bodies (rather than becoming angels, as is commonly referenced in Christian mythology).
Yep, a new spiritual body that puts on immortality. But the souls of the unsaved still have a mortal soul, i.e. they are still liable to die.
The last book of the Bible is called the ‘Book of the Revelation’, singular, not plural. Many Christians believe that our essence, our spirit, go to the Father upon our death. At Jesus’ second coming, we receive our ‘resurrection bodies’. Some believe that dead saints ‘sleep’ until ‘Judgement’.
Likewise, for those who do not believe in Jesus as Lord and Saviour, many Christians believe that these poor souls go to a region created by, and devoid of God, to spend eternity, Hell, in other words. Some Christians believe that these souls also ‘sleep’ until ‘Judgement’, when they are cast into Hell.
Since you refer to ‘Christian mythology’, am I right to assume that you do not believe in Jesus as Lord and Saviour, that this life ‘is it’? If that is the case, for your sake, I hope you are right. If you are wrong, eternity separated from God, is not something to look forward to.
