The message of the book of John is underlined by the use of two key words, believe, used ninety-eight times and life, used thirty-six times. In The Gospel of John, Elmer Towns places a particular emphasis on these words. The Apostle John wrote with a twofold purpose—as noted in 20:31—to communicate Christ through His miracles and teachings so men might, first, believe that Jesus was indeed who He said He was, the Son of God; and second, they might have eternal life because of their belief.
