The book's author is George H. Smith, who copyrighted his work in 1979. The 326 pages within it are of a philosophical and scholastic nature but make for an entertaining read. No thinking theist will be capable of undertaking this book and then intellectually holding fast to his fondness for God. The most revealing ideas in this work are found in the analyses of reason vs. faith, ethics, and Jesus Christ of Nazareth. Commitment to Christianity requires no thought, only emotion.
Human beings have a knack for being easily influenced.
It follows that most of us are easily influenced because most of us are human. I use my intellect to live my life from day to day. Thus, I find it amazing that people will ignore their knowledge and put stock in such things as God's existence and Jesus' love. When prospective Christians are proselytized, they are told that Christianity's foremost characteristic is love. If you are Christian, read George H. Smith's book and you might see this.
