Already a Kingdom in which the King offers redemption through his death and resurrection; not yet a kingdom in which redemption is applied to all of creation.
Already a Kingdom which one sees and enters through repentance and faith (John 3:3-5); not yet a kingdom which one sees with the physical eye.
Already a spiritual kingdom in which the King rules over the hearts and lives of his subjects, not yet, a geo-political kingdom in which all the universe is in subjection to His righteous rule.
Already a kingdom in which the subjects of the King are learning to love one another and live in unity; not yet a kingdom in which the subjects of the King perfectly love another and live in unity.
Already a kingdom in which its subjects hold title to an eternal inheritance; not yet a kingdom in which the subjects are in full enjoyment of the inheritance.
Already a kingdom in which its subjects are granted the New Heavens and Earth; not yet a kingdom in which they possess the New Heavens and Earth.
Already a kingdom which is in conflict with the powers of darkness; not yet a kingdom which is fully triumphant over the powers of darkness.
Already a kingdom in which the power of the King over death, disease, and the devil is evident; not yet a kingdom in which death, disease, and the devil are banished forever.
Already a kingdom growing mysteriously and gradually (Matt 13); not yet a kingdom manifested in power and glory.
