Faith itself is handed the keys, because the believing power in a person is what opens and shuts the inner chambers of consciousness. The kingdom is not a distant realm but the higher state within the body, and the 2 keys are the power to bind and the power to loose, to hold a thing fast or to let it go. What the higher self settles is then mirrored below in the outer life: heaven governs, and earth answers to it. The lower nature receives what the inner ruling power has already fixed. Every gate the awakening self locks or unlocks above shows itself afterward in the daily person.
What is decided in the higher chambers of the mind descends and takes form in the ordinary life of the body.
Keys: the twin powers to open and shut the inner states, to bind and to release
Kingdom of heaven: the higher state of consciousness within the body
Heaven: the higher ruling mind that decides first
Earth: the outer, bodily life that answers to what heaven settles
