When we built our home about 24 years ago, my son designed and constructed the interior. Unity (coordination), variety, and utility (function) all played important roles in his work.
When you step into a well-designed house, these elements tell a great deal about the purpose and character the house.
That's the way it is with the Bible. We'll apply this truth to the book of Philippians in Greek 2. Its "interior design" is absolutely amazing. The more you know about the patterns, styles, and construction of the various units in the book (there are 24 of them), the better you'll be able to determine the letter's purpose and unique character. This aspect of exegesis is unfortunately often neglected in Bible study. This is not all that surprising. A good design doesn't draw attention to itself. But upon closer look, you will see that both the form and the content of Philippians reflect a fabulous design (for my analysis, you can go here if you're interested).
"Pleasant and functional" -- that's how I'd describe our home Bradford Hall. I think the same two words could easily apply to the book of Philippians.
