Summary: A sermon about the realisation of God's kingdom.
A short novel I would recommend to anyone who is interested in pondering the mysteries of theology and spirituality is Flatland by Edwin A. Abbot, an English schoolteacher, theologian, and priest, which was first published in 1884.
Flatland is set in a two-dimensional universe, where everyone and everything are geometric shapes. The main character, who narrates the story, is a square, whose world is changed forever when he meets a sphere, a three dimensional being, who tells the square about the third dimension, then takes him out of his two dimensional world and shows it to him. After his discovery of the third dimension, the square contemplates the possibility of there being even higher dimensions.
Unlike the square and the other inhabitants of Flatland, we can perceive three physical dimensions, and we can think of time as being a fourth. And without directly saying so, Flatland implies there could there be higher dimensions in our existence we cannot directly experience.
In the late Nineteenth Century, physics was an assortment of different fields that had little - if anything - in common with each other. But all that changed in 1919, when German mathematician Theodor Kaluza wrote a letter to Albert Einstein that would change physics forever. Kaluza had been playing around with a physics equation, and incorporated an extra dimension into his calculations. And in doing so, he unwittingly managed to unite the previously unrelated theories of gravity and light. The ‘Holy Grail’ of physics is to unify and explain all physical phenomena in one single theory. Physicists haven’t quite got there yet, but Kaluza’s work showed that bringing theoretical higher dimensions we cannot directly experience into consideration can have some surprising implications.
Now I am not going to suggest the obvious and say higher dimensions that have been proposed in theory can explain heaven or any other spiritual place. But I will say though is that if science can propose the existence of higher dimensions we cannot directly perceive, it would not be unreasonable for science to accept the possibility of there being a spiritual realm that is distinct from our physical world.
Throughout the Bible there are many distinctions between the spiritual realm and our physical world, or in other words, between heaven and earth. The first verse in the Bible, which introduces the first creation story in Genesis, starts with the words:
1In the beginning when God created the heavens and the earth,”1
And tonight’s reading from the second to last chapter of Revelation, the final book in the Bible, tells us:
21Then I saw a new heaven and a new earth; for the first heaven and the first earth had passed away, and the sea was no more. 2
Revelation is arguably the most puzzling book in the Bible, so it’s probably not really surprising that some unsound exegesis around some of its fantastic content has led to the development of some really bad theology. But I digress. Its relatively sedate introduction of seven letters to seven churches in Asia to deal with local issues of the day soon gives rise to a hallucinatory nightmare peppered with images of multi-headed creatures, locusts with tails like scorpions, dragons, and various personifications of evil. Finally, after much toil and tribulation, Revelation concludes with the revelation of a new heaven and a new earth.
