In my understanding, the Kindom of God is the illuminated governance and guidance in an individual's life given by the power of the Holy Spirit ruling in the individual's heart, not earned but given by grace, after true and utter submission to God by accepting His Son, Jesus Christ as the Lord and Savior, and believing that he died and was rosed from the dead. The Kingdom of God is in the spiritual realm, where flesh dies with its sinful disires. Here, spiritual eyes open to see the good works of God, and spiritual ears open to hear the word of God, culminating into wonderfully strong desire and strengh to do only the will of God. Here, peace, justice and love reign as manifested by characteristic acts of giving, forgiving and helping, etc. each other.
