Have you ever wondered why we don’t use the names of any of the other world religions’ deities in our expletives? When we are angry, why don’t we say, “Oh, Buddha,” or “Krishna damn it?” The author, in his travels around the world, discovered that even the people of other religious cultures outside of Christianity use the names of God and Jesus Christ when they need a curse word of some sort for emphasis. In this booklet, the author examines the reasons why we use the most holy names of the Living God and of His Son, Jesus Christ, in vain. The tongue truly is the most unruly member.
