The words and books of the Bible, as we know it (Old and New Testaments) were each written for different purposes: some of it is written as historical fact, geneology, proverbs, allegory, prophecy (i.e., Daniel, Ezekiel, Revelation), song (i.e., Psalms), guidance for living (i.e., James, Ephesians), guidance to churches (Corinthians), etc. Different people wrote different portions, but all were moved by the Holy Spirit what to write, how to write, through individual perceptions and understandings (David, a king, wrote from a different perspective and for a different reason than did Luke, a doctor; Daniel, a prophet, wrote, also, from a different perspective and reason than did Paul, a Pharisee, Roman citizen, prior persecutor of the Christians, and one who never saw Jesus while He was alive). As we, individually, make up the Church, and bring our individuality and unique views to others for understanding, so, too, does this occur in the Bible. The differences, for example, between the four Gospels (Matt., Mark, Luke, and John), exist because four men focused on different areas of the same story (as many people viewing an accident see different things because each person is unique and sees the world from different vantage points). The "discrepancies" between the Gospels do not make one less or more accurate. They occur because one writer focused on something different, a different impression made upon and perceived by the writer, adding to the richness of the written Word.
Notwithstanding the fact that the original text was not written in English, human beings had to translate, and did so with great effort (and, I am sure some errors in translation), the Bible remains a living text, bringing different insight to each reader. (One individual can read a text one year which, if read again several years later, yields a different, perhaps, deeper meaning and understanding.)
There is, however, a central theme, or thread, throughout both Old and New Testaments: Looking toward a Savior for the world and Christ's deity. Everything written must be accepted by faith as the true Word of God. Just as not accepting the Bible as the true Word of God takes faith to disbelieve.
