Some basic presuppositions to hold to when approaching Scripture: the God of the Bible exists, God has revealed himself to ahis creation through the Bible, unsaved man cannot understand God's revelation, and a consistently used hermeneutic. (these presuppositions were modified from Dr. Christopher Cone's book Prolegomena on Biblical Hermeneutics and Method)
Hermeneutics or the science of interpretation is key in the development of a man's theology.
