Reading The Bible Wrongly

I never heard the Bible could be damaging until I read a book, Pai Desideria, by Phillip Spener in one of my history classes in seminary. Spener thought that people who read the Bible in the wrong way, for the wrong reasons, can actually be damaged by their reading. He wrote:

How many readers…do harm to themselves? If…they read without sincere prayer and the purpose to obey God, but only to get knowledge, to make a show, or to use what they’ve learned with pride and for their own glory.

Have you ever met any people who read the Bible the wrong way, for the wrong reasons? It seems to me that Jesus made mention of this several times in the gospels also. What do you think???
