The place Christians go after they die is not a non-material world, cloaked in white, filled with the sounds of a plucked harp. I hope that didn’t burst your bubble. But it’s true.
If you’re a Christian and you die before Jesus returns, you will experience two different Heavens. Why is that? Because there is a difference between the Heaven we go to when we die and the Heaven we experience when Jesus returns to Earth to make all things new.
