The kingdom of God is referring to the King of Kings who is abiding in you and is in union with you. You are in Him and He is in you. You are God's kingdom when you are rightly relating to the King as a son. Like Enoch it takes time to build a healthy, mature relationship with Abba. Being born of God is a process not a prayer. Your depth of relationship is initially evident if you just believe "God" is his name – you must GET to know Him.
