As we continue our reflections on the Sermon on the Mount, we’re reminded that Jesus goes far beyond behavior. His focus is the inner life—our thoughts, our words, our desires. We’ve just explored His teaching on murder, which doesn’t stop at the physical act but includes anger, contempt, and even careless words. Jesus was exposing a tendency—especially among the Pharisees—to shrink the scope of sin while expanding the space for self-justification. In doing so, they created a false sense of righteousness, thinking they could attain moral standing through selective obedience.
This is the nature of religion apart from grace. It creates systems in which people try to earn merit—where morality is treated as a checklist of dos and don’ts. But the message of the Sermon on the Mount shatters that illusion. Jesus sets a standard that is impossible to reach in our own strength. Why? Because God isn’t only looking at what we do—He is looking at who we are. And without His transforming presence in us, we simply cannot live up to the holiness He requires.
It Starts from Within
Jesus shows us that true sin lies deeper than behavior. It starts from within. As He says in Mark 7:23, “All these evil things come from within and defile the person.” So we’re not just dealing with external behavior—we’re addressing the inner person, the heart. Our problem isn’t just what we do; it’s who we are apart from God’s grace.
Before moving on to the subject of lust and purity, I want to say a few more words about anger. It’s something many of us struggle with—myself included.
In my own experience, I’ve noticed something odd: I sometimes treat inanimate objects as if they’re out to get me. It sounds strange, but when something goes wrong—a printer jams, a drawer sticks, traffic lights seem to conspire against me—I find myself reacting with irritation, even anger, as if those things were personal enemies. That’s a sign of something deeper going on.
What’s really happening is this: my goals are being blocked. I had a plan. I had a timeline. And when my expectations aren’t met, frustration builds. Anger often comes when I perceive that my needs are unmet, my rights are being denied, or my dignity is being attacked. And underneath that reaction is often pride—this subtle belief that the world should go the way I want it to.
But it doesn’t. And when it doesn’t, we need an antidote—something that reorients us away from ourselves. For me, that antidote has often been a single word: gratitude.
