A great many... have only an intellectual understanding without an actual experience in the soul. They... are often received as the children of God by those who do not discern between the "fellowship of the Spirit" and a mere fellowship of doctrine.

God's kingdom isn't outward, so we can't put outward definitions on it.... It's about God moving and working. He's a living, active God. So a certain outward form might have been good for a season, but He might want to change things in the future.
