Types of Writing in the Bible

The Bible contains a wide variety of types of writing yet all of the Bible teaches God's truth, despite the type of writing used. Some will no doubt argue that certain passages cannot be taken literally due to their being poetic in nature; but if that were indeed the case then by that same argument every other poem is also unable to teach truth. That a poem, or any other genre of literature, does not reveal its facts in narrative form does not in any way mean that it does not reveal truth. Definitely there are poems that are no more than entertainments or have been written merely to display the poet's skill but this does not prove that the words to the song sung at every child's birthday can mean anything other than that those singing it have sincerely wished their friend a Happy Birthday.
