Grace Is Not An Alibi

Grace That Will Not Let Us Go

We live in a world that is very good at explaining itself. Everyone has a reason. Everyone has a story. Everyone has an explanation for why things are the way they are. We explain our tempers. We explain our habits. We explain our compromises. And more often than not, those explanations slowly turn into excuses. “I grew up that way.” “That’s just who I am.” “God knows my heart.” “I’m only human.” And if we’re not careful, we bring that same habit into our faith.

Grace becomes our explanation. Grace becomes our cover story. Grace becomes our defense. We don’t say it out loud, but we live like this: Because God is gracious, this doesn’t really need to change. Because God forgives, this isn’t urgent. Because grace abounds, obedience can wait. Grace becomes an alibi. And that is exactly the misuse of grace Paul confronts head-on.

Imagine someone standing before a judge, guilty beyond question. The evidence is clear. The verdict is certain. But instead of sentencing, the judge does something unthinkable. He steps down from the bench, takes responsibility for the penalty, and declares the accused free to go. That’s grace. But now imagine that same person walking out of the courtroom and saying, “Well, since I was forgiven, I guess what I did doesn’t really matter.” “I’ll probably just keep living the same way.” At that point, grace hasn’t been received—it’s been misunderstood.

Because grace does not say, “Your sin was no big deal.” Grace says, “Your sin was deadly—and I paid the cost to free you from it.” And that’s why Paul asks the question that refuses to let us stay comfortable: “Shall we continue in sin so that grace may abound?” And then he answers it with the strongest words he can find: “By no means.” In other words: If grace has really taken hold of you, going back to sin shouldn’t even make sense anymore.

Paul doesn’t begin with behavior. He begins with identity. In Ephesians 2, he doesn’t say we were struggling in sin. He says we were dead in sin. Not sick. Not wounded. Not morally behind. Dead. And dead people don’t need improvement. They need resurrection. That’s the heart of justifying grace. God does not come along to make bad people better. He comes to make dead people alive. Salvation is not self-help with divine assistance—it is new birth, new standing, new life. And that’s why Romans 6 matters so much. Because if we have been buried with Christ and raised with Him, then continuing in sin is not just disobedience—it’s living like someone we no longer are. Grace saves us from sin, not in it.

The sermon for the first week we talked about drift - we were warned about drifting without noticing. Today we see the danger of standing still after seeing clearly. Drift happens when we stop paying attention. But stagnation happens when we refuse to respond. Grace will always show you who Jesus is— but it will never let you stay on the mountain pretending that’s enough.

That grace will smooth things over. That grace will understand. That grace will wait. But today—on Transfiguration Sunday—Scripture interrupts that assumption. Because the Transfiguration is not a gentle reminder. It’s not Jesus affirming the disciples exactly as they are. It’s not grace patting them on the back and saying, “You’re doing great—carry on.” It’s a moment where God pulls back the veil and says, “This is who Jesus really is.” And once you see Him clearly, you can’t pretend nothing needs to change.

Illustration – When Seeing Clearly Changes Everything

(Matthew 17:1–9) Jesus takes Peter, James, and John up a mountain—away from the noise, away from the crowds, away from routine. And there, right in front of them, He is transfigured. His face shines. His clothes blaze white. Moses and Elijah appear. Glory breaks through the ordinary. And the disciples do what we so often do when grace gets uncomfortable. Peter tries to manage the moment. “Lord, it is good for us to be here. Let’s build some shelters.” In other words: Let’s stay right here. Let’s contain this. Let’s freeze grace in a moment we can control. But grace will not be managed. Before Peter can finish his sentence, a cloud descends and a voice thunders from heaven: “This is my Son, whom I love; with Him I am well pleased. Listen to Him.” Not admire Him. Not explain Him away. Not domesticate Him. Listen to Him.

And when the voice fades and the glory recedes, Jesus touches them and says, “Get up. Don’t be afraid.” Then He leads them back down the mountain—toward the cross, toward obedience, toward transformation. Grace doesn’t trap them in the moment. Grace sends them forward changed and into a life that was going to be filled with pain, heartbreak, panic and tears.

Paul asks the question that exposes our faulty logic: “Shall we continue in sin so that grace may abound?” In modern language, Paul is saying: If grace always shows up after sin, does that mean sin is actually helping grace do its job? That’s a logical fallacy. A spiritual post hoc ergo propter hoc. Just because grace follows sin doesn’t mean sin caused grace. And just because forgiveness comes doesn’t mean approval was given. Paul’s answer is sharp because the stakes are high: “By no means! How can we who died to sin still live in it?” Grace didn’t arrive to excuse the old life. Grace arrived to end it. Then Paul goes even deeper. He ties grace to baptism: “We were buried therefore with Him by baptism into death, so that, just as Christ was raised from the dead… we too might walk in newness of life.” That’s not improvement—that’s resurrection.

Dead people don’t negotiate with sin. Dead people don’t drift. Dead people don’t manage habits. Dead people are raised—or they remain dead.

Transition – Tying Transfiguration to Justifying Grace

On the mountain, the disciples were given a glimpse of who Jesus truly is. The veil was pulled back. Glory broke through. And for a moment, everything was clear. But the Transfiguration was never meant to be a place to stay—it was a moment that demanded a response. The voice from heaven didn’t say, “Remain here.” It said, “Listen to Him.” Remember last week where we looked at paying closer attention? Seeing clearly was only the beginning.

And that’s where Paul takes us next. Because once Christ has been revealed, the question is no longer who He is—the question becomes who we are now because of Him. Grace doesn’t stop with revelation; it moves toward transformation. Paul refuses to let grace become something we admire from a distance or misuse as an excuse to stay the same. If we have truly encountered Christ, then something fundamental has happened to us.

So Paul asks the question that forces us off the mountain and into real life: “Shall we continue in sin so that grace may abound?” And his answer is immediate and uncompromising: “By no means.” Because justifying grace doesn’t invite us to linger where we are—it declares that the old life has been buried and a new life has begun. Grace doesn’t preserve the past; it creates a future.

Peter wanted a tent. Jesus wanted obedience. Grace is not an alibi to stay. Grace is the power to move.
