In the ancient world cities were nearly nations unto themselves – they existed within walls, with their own laws and customs, generally centered on the common purpose of trade. This is not as much the case in the modern world, but we still tend to divide ourselves city by city in terms of sports teams, accents, music and culture, and still tend to generalize the character of people from other cities. It follows, then, that in the Bible cities represent various doctrines – collections of inter-related ideas about spiritual reality. Such doctrines can be based on anything from the Lord’s true teachings – the New Jerusalem seen by John in Revelation – to the falsity and heresy of Sodom and various cities obliterated by the people of Israel at God’s command. On the most personal level, a city can also represent the natural mind of one person – which makes sense since we each to some extent have our own doctrine and our own set of ideas and beliefs.

I have noticed that those in heaven dwell beneath a clear, bright sky like that of morning and midday, extending also towards evening, and likewise in a warmth like that of spring, summer, and autumn. But those in hell dwell under a dim, cloudy, and darkened sky, and also in the cold [of winter]. I have noticed that between the two in general a balance is kept; also that insofar as love, charity, and consequently faith are present in angels, they dwell under a clear sky and in the warmth of spring, and that insofar as hatred and consequently falsity are present in those in hell they dwell in thick darkness and in coldness. And as stated above, the light in the next life holds intelligence within it, the warmth love within it, while thick darkness holds insanity within it, and cold hatred within it.
