125. Various comparisons may be used as illustrations of the fact that Jehovah God could not set in motion and produce such results except through His Human. For instance, an invisible man cannot shake hands with or talk to anyone except someone who is visible; not even an angel or a spirit can do so with a person, although he stands next to him or right before his face. Neither can anyone's soul talk or deal with another person, except by means of his own body. The sun cannot penetrate any person, animal or tree with its light and heat, unless it first penetrates the air and acts through it; likewise it cannot affect fish except through water.. It must act through the element in which the subject is. No more can anyone take the scales off a fish without* a knife, or pluck a crow without fingers; or go down into the depths of a lake without a diving bell. In short, each thing must be suited to the other before communication can be established, and work can be done either against or with it.
