Coming in the Clouds: An Evangelical Case foe the Invisibility of Christ at His Second Coming

This book commences with the cloud in creation, functioning as a symbol of the trancendence of God and the means by which he creates, and continues with the descent of God in the cloud in making covenant with Abraham and Moses. Otto describes the cloud leading Israel out of Egypt and providing for her physically and spiritually, culminating in the great theophany on Sinai.
