Rhyme & Reason: The Science of Bible Study

Brethren,
One of the primary rules of reading and interpreting Scripture is to always consider the context of the passage.  When applying this rule, we should take care to consider both the immediate and grand-narrative contexts.  We do this by asking ourselves: How does this passage fit within its Book as well as how it relates to the whole of Scripture?
The Book of Hebrews is a daunting read that can be simplified by applying this very rule. Take, for instance, the Melchizedekian priesthood in chapter 7.  It seemingly comes out of no where within its Book, but is mentioned in various forms throughout the Old Testament.
And just in case you were wondering or have ever wondered as to the significance of the Melchizedekian priesthood along with its relationship to the more familiar Levitical priesthood, read the article linked below?  It will serve to further solidify the importance of the rule above.
