All things change. The concept of us being servants of God is not the exception. It is an idea and is not exempt from the laws of nature, the laws of perpetual change. Nothing stays in a perpetual state of equilibrium, including our perception of ourselves, in spite of what religious institutions may desire. Things either eventually change through growth or things change through erosion.
Religious institutions are no different.
They cannot wish away the unnatural state of equilibrium just because they do not want to change. Nobody likes change and religious institutions are no exception. They can either accept change and grow or they will erode away as do all things in nature. Now for the concept of God. Religious institutions defy the laws of nature through professing that God is in a state of equilibrium.
