Book excerpt: This book Dove of Gold approaches the vast subject of the Holy Spirit by viewing His functions through illustrations He Himself has selected as vehicles for the revelation of His character and work. In both the Old and the New Testaments several carefully chosen and highly suggestive symbols picture His activities. They have to do with natural objects, and through them the mind can easily pass from the known to the lesser known. Imagine each symbol to be a many-faceted gem. Lift it up, and allow the light of the Sun of Righteousness to fall upon it. Turn it around, and observe the flashing of light from each facet. Such study requires leisure and careful thought. As one observes the related aspects of the nature and function of the natural object used as a symbol, the work of the Holy Spirit will become clearer, and His disposition of concern and affection much more appealing.
