Are we quite sure that we are receiving now the Kingdom which cannot be shaken? Note the language, note the tense. "Wherefore receiving (present active) a kingdom which cannot be shaken". It does not say the Kingdom is going to come; the Kingdom has been introduced, and the Kingdom is going to be consummated: it is progressive and it is spiritual. The question, put quite bluntly, is this: Are we quite sure that we are founded and grounded in the spiritual and the heavenly realities of Christ and His cross, or are we simply linked up with some system of truth, doctrine, practice? Are we dependent upon the externalities of our faith, or have we the risen, living Lord resident in our hearts, and is He answering to all the need of our spiritual life, as represented by that system which has been put aside?
