I don't know what heaven will be like, or even if there is a heaven. Maybe we each will have our own kind of heaven... or hell. Maybe it will be after we die, or maybe it's here right now. In that case, we would experience both heaven and hell at different times. As a person with bipolar disorder, this makes sense to me: I know about experiencing the extremes.
The American poet Wallace Stevens wrote, skeptically and with exasperation, about the hereafter in his poem "Sunday Morning." He wrote:
Is there no change of death in paradise?
Does ripe fruit never fall? Or do the boughs
Hang always heavy in that perfect sky,
Unchanging, yet so like our perishing earth,
With rivers like our own that seek for seas
They never find, the same receding shores
That never touch with inarticulate pang?
Why set the pear upon those river banks
Or spice the shores with odors of the plum?
Alas, that they should wear our colors there,
The silken weavings of our afternoons,
And pick the strings of our insipid lutes!
He's saying that a life of porcelain-like permanence would be no heaven, even though it is perfect. Indeed, for Stevens,that kind of paradise is anti-life, at best an insipid reflection of the rich beauty we know in our world.
It's commonplace to think that heaven is a perfect place, and I suppose many people believe that it's unchanging. But is it? Why should it be? I agree with Stevens that a heaven frozen outside space and time is a very uninviting place. I wouldn't want to go there.
Perfection implies unchangeability. If it changed, it wasn't perfect, was it?
Change is the essence of life, so would it not also be the essence of heaven? Can heaven be static? Death is static.
There may be a heaven where everything is static and perfect, but in this life the best we have are ecstatic experiences that occur only rarely. I suppose one hope we might have for heaven would be to have these ecstasies wrapped into one unending tremulo.
