125. That Jehovah God could have entered upon and have accomplished such a work only by means of His Human may be illustrated by various comparisons; as, that one who is invisible cannot shake hands or converse with another until he becomes visible; thus an angel or spirit could have no interaction with a man, even if standing close to his body and before his face. Neither can anyone's soul converse with another or act with another except by means of his body. The sun with its light and heat can enter into man, beast, or tree only by first entering the air and operating through it; or can enter into a fish only by means of the water, since it must act through that element in which the subject resides. No one can scale a fish without a knife, or pluck a crow without fingers; or descend to the bottom of a lake without a diving-bell; in a word, anyone thing must be adapted to another before it can communicate with it or operate with it or against it.
