You can possess the most beautiful, detailed and well thought out set of blueprints for a house, but without a competent general contractor to execute those plans, the structure does not get built. The plan is worthless without someone to build it.
You can have the perfect blend of DNA -George Clooney's good looks, Einstein's intellect, Michael Jordan's athletic ability. But your genetic make-up would stay dormant without an innate intelligence to turn the sequence on, yielding the perfect end product. The code is of no use without Life.
In medicine, most of the emphasis is placed on the blueprint's (DNA's) influence on health, while in Chiropractic, the influence is rightly given to the Power that creates and animates the matter initially. The former is USELESS without the latter.
