The height of a building has long been connected with its importance; city centers are populated with tall skyscrapers to demonstrate the prestige of the city and of the companies that own them. In the case of buildings devoted to the worship of God, this connection is even more pronounced. Historically, churches have been the tallest buildings in a given area. Their towers and domes can be seen for miles around, pointing to the presence of the House of God. In this sense, the church building evangelizes from a distance. Some have said that the building “preaches” simply by its heavenward focus. Even in an age of GPS technology, the church tower continues to be a directional sign. It is a compelling reminder of the presence of God in our world.Visible churches are not simply gathering places but signify and make visible the Church living in this place, the dwelling of God with men reconciled and united in Christ.”
