The biggest thing that want to learn more about is serpent handling at religious ceremonies. I have never heard of that before in my life until I read the profile in the book. It is found in a small number of Pentecostal churches in the U.S. They believe that they will cast out devils and speak new tongues. It says that nothing shall ever hurt you, not even the most poisonous of creaters. As it says in the book of Mark from the Holy Bible, "And these signs shall follow them that believe: In my name shall they cast out devils; they shall speak with new tongues. They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover." The book of Luke from the Holy Bible also has a passage saying, "Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you." The snake handlers are supposed to lay their hands on the sick, speak in tongues, provide miracles, and occasionally consume poison to prove that it can't hurt them with the power of God. I thought this was very interesting to learn more about.
