Everyone has an ultimate source of Authority in their life. It may be peer-reviewed journal articles, opinion polls, text books, professors, personal experience, feelings, impressions, or what your parents taught you growing up. However, it is impossible to live without a final authority. Who or what do you turn to as the final court of appeal in your life? If you are a Christian, then your final authority must be the Bible. This is why the Apostles really matter.
