Many people who think they’re Kingdom citizens will someday be shocked to discover they aren’t. In Matthew 7:21 Jesus says, “Not everyone who says to Me, ‘Lord, Lord,’ will enter the kingdom of heaven; but he who does the will of My Father who is in heaven.” Some people think highly of the Kingdom but never receive the King. They call Jesus “Lord” but don’t do His will. Lip service won’t do. You must receive the King and His Kingdom (John 1:12).
