Defend your answer. Must be  300 words and  2 references and citations in APA format (with the exceptions that single-spacing is appropriate in the discussion boards and that you will not be penalized if the references in the discussions are not in hanging indentation format due to the difficulty that sometimes occurs with formatting discussions).

The Bible and additional sources may (optionally) be incorporated in addition to the 2 sources from course materials or other scholarly sources.
