Dr. Geisler clearly sets forth the reality of the existence of God, and explains and describes His attributes and characteristics, among them His actuality and simplicity, life and immortality, unity and trinity. Geisler concludes this study by illustrating how we must respond to God’s attributes with heart, mind, and strength. He then turns to the activity of God in the section on Creation. Here, Geisler studies the biblical understanding of God's work—past, present, and future. He explains the scientific views associated with the creation of all things, including the origin of spiritual creation. The section culminates in a discussion of God’s relation to His creation.
