This book was written to put forth the concept that since those who were ignorant of the reality of God, worshipped him according to their own lack of understanding; they simply worshipped what was commonly characterized as a spirit.
In the schools of thought today universally, the two major camps are "believers and non-believers." There are those who say they believe in God as a spirit and those who say that since they cannot empirically substantiate the reality of God, he or it doesn't exist.
