Beyond the Boss Battle: Why Being "Good Enough" is a Dead End

A Summary of the Katy Bible Sermon “Theology Matters”, preached by Matt Mancini on March 15th, 2026.

I remember coming to each new semester, during my college years, staring at a literal mountain of theology textbooks. One systematic theology textbook alone was over 1,300 pages long! If I approached those books as a massive obstacle to overcome, I might have been completely overwhelmed. I might not have made it through.

As a way to motivate myself, I turned my reading list into a game. Each book became a "boss battle".  This was my way of reframing the struggle. Every time I finished a volume, I had defeated another boss and could move on to the next challenge.

In a sense, Paul is doing something similar in the book of Romans. Since the beginning of chapter three, he has been "beating bosses" by anticipating and addressing every objection someone might have to the Gospel of justification by grace alone through faith alone. First, he defeats the boss of “works” in Romans 4:1-8. Then, the boss of “religious ceremony” in Romans 4:9-12. In Romans 4:13-17, he faces the third and final boss: the principle of “law”, or what we often call “legalism” or, more broadly, “moralism.”

The Geography of Salvation

Many of us live under the crushing weight of trying to be "good enough." We view our spiritual life as a climb. But as the late Donald Grey Barnhouse once pointed out, this “ascent” is a dead end. Barnhouse used a brilliant analogy called “The Geography of Salvation” to explain why this climb is futile.

In the United States, the lowest point (Death Valley) and the highest point (Mount Whitney) are both located in the same state: California. Imagine if you were standing in Death Valley and you climbed all the way to the peak of Mount Whitney. Sure, you would have made some progress in elevation, but you would still be in California.

This is the problem for the moralist.  You can attempt to climb the mountain of morality, striving to become the "best version" of yourself, but in the end, you’re still in the same lost state. You may be better than you were, morally speaking, but you have only succeeded in becoming a “better sinner.”

You don't need a higher moral elevation; you need a complete change of state. You don't need a new set of moral standards; you need a new nature. As the Bible reminds us in response to the excuse of “I was born this way,” the answer is: "Exactly... which is why you must be born again."

The $5 Million Vertical Jump

To understand why relying on the Law, or our own "goodness", makes God's promises worthless, let’s consider this scenario: Imagine I climbed onto the roof of our church and offered you $5 million in cash. I could even show you the money and sign a binding contract. But the condition for receiving it is this: you must make a single standing vertical jump from the ground to the roof.

In one sense, that is a legitimate promise. But in reality, the promise is worthless to you because the condition is impossible to meet. If the promise of heaven is predicated on absolute moral perfection, then the promise is effectively nullified because no fallen sinner can ever meet that standard. If God gave the promise through the Law, He would be giving with His right hand what He takes back with His left.

A Mirror, Not a Ladder

So, if the Law can’t save us, does that mean it’s worthless? Of course not. The Law is holy and good, but we often misunderstand its job. The Law was never meant to be a ladder; it was meant to be a mirror.

A mirror’s job is to show you that your face is dirty. You wouldn’t declare a mirror defective because it can not wash your face. That is not its job. In the same way, the Law shows us our "spiritual dirt"—the reality that we are still sinners, though we might have had presumptions of self-righteousness. The Law isn’t meant to cleanse us; it’s meant to drive us to the One Who can clean us—Jesus Christ.

From the Womb of Doubt to the Broad Day

When we stop trusting in our "moral elevation" and begin trusting in God's grace, our theology matters in a deeply practical way. Moralism, the belief that our salvation depends on our performance, is the “womb of doubt.” If your salvation rests on how good you are, you can never be sure. You will always be wondering: How honest is honest enough? How many good works are sufficient? You end up walking in a perpetual night, your footsteps echoing with the "hysteria of doubt."

But the person who walks by grace walks in the "broad day." Because our justification rests entirely on the finished work of Christ—a work we can add nothing to—we can have an assurance that is certain and absolute. This certainty isn't arrogant; it's faithful. To say we can't be certain of our salvation is actually blasphemous, because it suggests that what Christ did wasn't enough.

This week, stop looking at your own footsteps and start looking at the light of God’s promises. You aren't justified because you beat the boss; you are justified because He did.
