I have just recently finished going through the book of Proverbs. The beginning was great, but once you hit chapter ten, you get these endless lists of pithy sayings and it pretty much carries on like that until the end of the book. It was pretty tough going at times, but last night I finally hit the final chapter. And what a chapter! It ends with a description of the perfect wife.
Since Christ is the Wisdom of God, the righteous heroine of Proverbs (see for example chapters one and eight), the righteous woman depicted in this chapter is probably also a depiction of Christ. Being betrothed to Christ is the greatest privilege any man (or woman!) can ever know.
