58:13 In his isolated home John was able to study more closely than ever before the manifestations of divine power as recorded in the book of nature and in the pages of inspiration. To him it was a delight to meditate on the work of creation and to adore the divine Architect. In former years his eyes had been greeted by the sight of forest-covered hills, green valleys, and fruitful plains; and in the beauties of nature it had ever been his delight to trace the wisdom and skill of the Creator. He was now surrounded by scenes that to many would appear gloomy and uninteresting; but to John it was otherwise. While his surroundings might be desolate and barren, the blue heavens that bent above him were as bright and beautiful as the skies above his loved Jerusalem. In the wild, rugged rocks, in the mysteries of the deep, in the glories of the firmament, he read important lessons. All bore the message of God's power and glory.
