Heaven is located BEYOND the fourth dimension. Mostlikely in the fifth dimension.
This is most likely true. We know a few things:
most people go through a tunnel to get there, after death.
Heaven is more real, more concrete than earth, so it has an actual locality, but we can’t get there by physical travel.
We are surrounded by the citizens of heaven right now,
the saints and angels are all around us, though usually we can’t see them.
As Jesus said, you don’t even understand the things of earth when I tell you, how could you understand the things of heaven?
I think of it as if we were unborn infants: the fetus doesn’t know what life will be like outside the womb. If he were capable, he would fight to stay in the womb. But he will die if he does, as he’s meant to be born and grow into an adult human being.
We fight to stay in this life, having little idea of what the next life holds. But we are meant to pass to the next life and grow into our full potential as human beings in Christ.
Death is the one adventure that no one can avoid.
