I've never liked the cliché, "Curiosity killed the cat." Curiosity can be a good thing. In its basic form, curiosity is a strong desire to know or learn something. It fills the gaps in knowledge. It is often counterintuitive. Curiosity motivates one to seek knowledge or understanding that one would not usually expect. Curiosity is essential to being contrarian. If you oppose or question conventional wisdom, then you've got a curious streak in you. I'll leave cats to do what cats do. If curiosity can keep me from being a sheeple, then I'll take the risk.
What is the primary question category of a curious person? The big probing questions are who, what, where, when, why, and how. I think one of the most important is why. Granted, a child asking why over and over again can get quite annoying, but it serves a valuable purpose. How else are they going to learn things or gain a better understanding of things? Why seeks to get to the heart of the matter.
Today's passage begins with a why question. Verse 19 begins with the rhetorical question, "Why the law?" Paul was inviting the Galatians to think about this question with him. "Why the law?" If the universe was created by a personal God who does all things according to His purpose, then it's a good thing to ask why questions. "Why then the law?"
