Definition: Realm: A geographical concept that encompasses a specific area or a group of areas where a person lives, works, or has some connection to. Realm is used in theology for a place where God's Word is found (John 14:26) and can also refer to an entire set of biblical teachings or a denomination (Acts 7:58). It's not just about space, but rather the people, places, and things they belong to. The term comes from Greek realms, meaning areas.
