What has been incorrectly titled "The Lord's Prayer", is actually "Our Prayer." We are taught by Immanuel, God in the flesh, how and what to pray for. In Matt.6:10: Thy Kingdom come. Thy will be done in earth, as it is in heaven.
John the Baptist preached Repentance. Christ taught Repentance. Christ Disciples taught Repentance - and so should we. The second part of Their sermon was: For the Kingdom of heaven is at hand. Christ was The Creator of all living. He established His Kingdom on earth for those able to be in a right-standing relationship with Him.
Repent = a mind change. Turning with contrition, from the world, to the Lord[YHVH].
Kingdom = royal power, kingship, dominion, rule. A kingdom, the territory subject to the rule of a king.
Heaven = Spirit. So is Christ, the Written Word, and the Holy Spirit.
Christ gave us parables that contain both the Kingdom, and the world; Spiritual flashlights are required for understanding.
Christ stated "In My Father's house are many mansions." This is Kingdom of Heaven talk.
The world id divided by Two - that can Not change: The Tree of Life, and the Tree of Knowledge, of good and evil. The Kingdom of Heaven on earth, represents Life. The kingdom of Knowledge represents the world, and death.
Specifically, where is the Kingdom of Heaven? It is inside of our brain - which must be "renewed" to see the Spiritual that we are a part of [Rom.12:2]. The world is doomed and can Not be saved; that why the Kingdom of Heaven, on earth, is the only choice.
