We often think of sin as a series of isolated events, a lie here, a moment of anger there. We view it as a "mistake" we can just sweep away. But in reality, sin is more like a biological process. If a caterpillar never changes, it doesn't just stay small; it eventually becomes a destructive force to the very plant it lives on. And for us, living "according to the flesh" isn't a harmless hobby; it’s a predatory force that produces a very real, very painful rot in our lives. Today, we’re facing the present danger of the caterpillar life.
