Kenneth E. Hagin believes that training the human spirit is the key to success in all areas of life. The spirit grows through the study of God's Word. Science has spent millions of dollars to develop the physical body and the intellectual processes of man. But little has been done about developing man's spirit. In Rev. Kenneth E. Hagin's book The Human Spirit, you will learn to: Develop your spirit nature. Meditate in the Word of God. Practice the Word of God. Give first place to the Word of God Obey the voice of your spirit
