Given the recent interest in matters pertaining to the afterlife and heaven, I decided to skim through Barth’s section on the kingdom of Heaven in Church Dogmatics III.3. To be clear, I was only able to skim, as I have other responsibilities at hand, so I am not able to give a distillation of the material.
In the process of skimming, I came across the following paragraph in an excursus, and I thought y’all would enjoy it. For Barth, heaven is “inaccessible” though “a created place like earth itself and the accessible reality of earth which we can explore and describe or at least indicate.”
We have not so far considered all the biblical statements from which it emerges that the Old and New Testaments see heaven as a cosmic reality constituted and consolidated by the fact that, as there is an operation of God from heaven, so there is a being of God in heaven. …To the real whence of the divine activity there necessarily corresponds a real Where of its origin, a real place of God as its Subject and Author. This real place of God as the Lord acting in the world is heaven. Even heaven would not be a cosmic reality in the biblical sense if it were only the Whence of the divine activity and not as such also the Where, the place of its Subject and Author. The former itself would not be true without the latter. Heaven is a place: the place of God in view of which we have to say that God is not only transcendent in relation to the world but also immanent and present within it; the place of God from which His dealings with us, the history of the covenant, can take place in the most concrete sense, and His majesty, loftiness and remoteness can acquire the most concrete form, where otherwise they would simply be a product of human fantasy. As the place of God heaven is, of course, a place which is inconceivable to us. It cannot be compared with any other real or imaginary place. It is inaccessible. It cannot be explored or described or even indicated. All that can be affirmed concerning it is that it is a created place like earth itself and the accessible reality of earth which we can explore and describe or at least indicate; and that it is the place of God. The final point is the decisive one. And for good reasons the Old and New Testaments do not hesitate to speak of the fact that God is in heaven and heaven is the place of God.

On a related topic, I once posted on Barth’s doctrine of angels: “To deny the angels is to deny God Himself.”
