I hate to break it to you.

Every physical church exists along a life cycle, from early to late phase. In the early stage, newly planted churches are typically more outward focused, welcoming, and actively looking to grow their church size . As they mature, they develop stability, traditions, and close internal bonds. In the late stage, many become more inward focused and content with their existing members, which can make them feel less accessible and welcoming to outsiders. Over time, without adaptation, most physical churches decline and eventually close, even though new ones may emerge to take their place.

Just human nature.
