Strategies for pursuing the biblical-theological ideas that run through scripture

1. Let the Bible be what it is, and be open to the notion that what it says about the unseen realm might just be real.
2. The content of the Bible needs to make sense in its own context, whether or not it makes sense in ours.
3. How the biblical writers tie passages together for interpretation should guide our own interpretation of the Bible.
4. How the New Testament writers repurpose the Old Testament is critical for biblical interpretation. Also called intertextuality.
5. Metaphorical meaning isn't "less real" than literal meaning (however that's defined).
