When police broke into an apartment in Sydney in January 2008 and found the decomposed body of 61 year-old Jorge Coloma 
(here),  there was much community discussion of how his absence could have gone  unnoticed for over a year. He had died from natural causes in his  bedroom. No one noticed that he'd disappeared. Even a pile of twelve  months worth of mail and unpaid bills did not lead anyone check to his  apartment or call the police. It took a year before neighbours felt that  something was wrong. People asked why authorities had not done  something. Others wondered about his family; wasn't there one family  member that had missed him? Neighbours also began to ask themselves  questions, why hadn't they spoken up much sooner? Jorge's story and many  others like it are the dark side of city life, but there is another  side.
The Bible depicts the new restored and redeemed world as a city.   Jesus revealed to John what God had in store for his people, he saw '
...the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband'  (Revelation 21:2).  The city is not an evil aberration that is a  consequence of the fall, but rather it is a form of human settlement.   Jeremiah (29:5-5) commended the survivors of Israel after the  destruction of Jerusalem and their exile to Babylon with the words of  God that they were to:
"Build houses and settle down; plant gardens and eat what they produce. Marry and have sons and daughters; find wives for your sons and give  your daughters in marriage, so that they too may have sons and  daughters. Increase in number there; do not decrease. Also,  seek the peace and prosperity of the city to which I have carried you  into exile. Pray to the LORD for it, because if it prospers, you too  will prosper."
The remnant of Israel were to build towns and ultimately cities and to contribute to their good.
Understanding the importance and role of the city
Cities  can be lonely places, where it is easy to be anonymous or to lead an  isolated life. They can be places where people like Jorge can die alone,  and where others can suffer physically and emotionally alone and  without support. Cities are places where homelessness is common and  abuse of one kind or another a daily part of life.
But they are also  places of rich culture and learning, places where ideas are exchanged  and people's lives can be enriched. They are places where Christians can  preach and share the word of God, serve the sick and needy, train and equip  others for ministry and life, raise a family, be part of the delivery of  God’s grace to lost people.
Tim Keller has pointed out that the human  desire to congregate inevitably leads to the formation of cities as  people congregate together for security, to share resources, for  commerce, to learn from one another an so on. Keller suggests that if  you capture the city with the gospel you capture the nation (
here).  The city he points out can be a wonderful place to live and raise a family (listen to his talk 
here). It is a strategic place to build gospel ministry.

As  Christians it would be easy to assume that the city is a sinful  wasteland and retreat to the peace and tranquillity of a remote farm to  live a life of isolation, but that is not what we are generally called  to do. Cities are places over which God is sovereign where he is at  work, and as always they are strategic, because it is in cities that  many people come together to work, trade, learn, play, create, perform  and so on. There is much talk about the impact of technology on human  activity - new ways to travel, instant forms of mass global  communication, new ways to connect or ‘wire’ communities (see previous  posts 
here and 
here)  - but while technology is changing the way we spend our time, where we  spend it, and how we communicate with one another, the need for human  contact remains and community remains. As such, the buildings and  physical buildings and spaces we create should reflect our desire to be  with other people, to share our lives and the gospel others.
What are the implications of the above?
How does the above inform the way we use the space that we  live in at home, the way we think about the role of space and property  in gospel ministry, the way we engage with and seek to build our local  communities? A few quick thoughts on practical ways that we can think  about these issues.
 a) Our houses
a) Our houses  - if we need to choose a house or apartment to rent, or we're fortunate  enough to be able buy one, we should look at the property with  community eyes. How easy will this property make it to get to know my  neighbours? Is it open in design or closed? How is the space within the  property conducive to family life and offering hospitality to others?  Can I see other people from my apartment balcony, the front veranda, the  front or back yard? How long will it take me to get to work, church,  the people I care for, and so on (loss of time due to travel is  important)? Such thinking turns on its head the way we generally think  about our real estate. As well, within the apartment or home, is there a  good mix of individual and shared space? If raising a family we should  avoid creating personal retreats equipped with all one needs for  individual survival. Don’t locate televisions and computers in  children’s bedrooms. If you are building a house, don’t cover the block  with house at the expense of yard.
 b) Church buildings
b) Church buildings  – When designing, renovating, relocating or extending church buildings,  we need to think about the type of spaces that we create in the church  and how we use it. Rows of pews facing a high alter will have a  different effect on communication and interaction than seats in the  round or even at tables. Our traditional church buildings with stained  glass windows and grand facades were designed like the temple to be seen  from afar and to draw people to them. While accepting that heritage  issues will prevent us making too many changes to such buildings, we can  praise God that they are often in the best locations in town. We can  also change how we use space inside them and how we use their location  and their use to establish relationships with the people living near us.  If locating a new church we need to consider all options for where we  place it, what form the building should take and whether it will serve  ministry to one another while ‘connecting’ with our communities. Of  course the activities we develop in and from the building and the way we  live our lives within the community will matter, but the buildings and  their spaces do make a difference.
c) The city around us  - As citizens within a city what are the things that we should join  others in advocating? While Christians represent a small proportion of  citizens how can we use our voices and sometimes public and professional  positions to influence public decisions about our cities? And how can  we use the spaces we have? In relation to planning we should be  supportive of:
 
- More and better public spaces (parks, playing fields, walking tracks, cycle ways etc).
- Better public transport, pedestrian ways, cycle ways, spaces to  encourage people to congregate (see Tim Chester’s thoughts on this here).
- Careful planning to integrate commercial, residential and  recreational spaces in ways that make human movement easy, that  increases visibility (for safety as well as community building), that  reduce isolation and the need for long distance travel.
