This book is written with five main themes. They are the: evolution of man, evolution of the spirit, spiritual development, spiritual warfare and the destiny of man. The first one is called the evolution of man. The essentials are that man was created a natural being. When he accepts Jesus Christ as his Lord and Savior, he becomes supernatural. The destiny of man is to become a glorified creature. (Phi 3:21) This happens at the rapture.
