In reality, it is the building that you have. It is a mistake to demean it by denying it is the real church or treating life in the building as temporary. Demeaning the building interferes with a positive congregational identity and leads to less care rather than more care of the space. Growing congregations make lemonade with lemons. When new congregations stop growing they most frequently blame their buildings and space.
Space is practically never the primary problem.
Plateaus of growth are transcended by attitudes towards visitors, systems to incorporate new members, and understanding large group organization. Growing a congregation is working against gravity. There are daily pulls to plateau. The institutionalization of procedures and focusing on the current members pulls us away from growth. The need for intimacy can be accomplished either by being a small congregation or by finding ways to ensure intimacy in a large one.
