The central message of this sermon is that wisdom, as understood in a biblical context, is essentially about skillful living. It's not just about intellectual knowledge or abstract intelligence, but rather about recognizing and initiating the causes that produce desired effects in various areas of life. The teacher argues that wisdom understands cause-and-effect relationships and conducts itself to produce the desired outcome, whether it's in gardening, relationships, finances, or any other aspect of life. This understanding of wisdom implies that God desires us to live skillfully, acquiring insight and applying it throughout our lives to produce a "thing of beauty" that blesses ourselves, others, and ultimately, God. The sermon suggests that this concept of wisdom is not just abstract, but rather a lived-out reality that can be developed through understanding the rules of the created order and navigating them effectively.
