Proverbs is a practical book filled with "sound bites" of God's wisdom. As we read, we need to remember that a proverb isn't a promise that God will always respond to our behavior in a certain way, but a memorable phrase that points to truth beyond itself. Proverbs are God's guidelines for wise living, not his guarantees for prosperity or blessing.
