In the natural realm, a frontier marks a specific geographic location. It is static and once crossed what was previously a mystery becomes known. In the spiritual realm, a frontier is a mobile and always advancing line that moves the marker of what was known farther ahead of us toward a distant and eternal horizon. Spirit-breathed revelation takes us on a journey into unexplored places of faith. Never settle. Always be willing to journey with God past old frontier markers into the never-ending and always expanding depths of His revelation.
