March 19 Sermon: Speaking the Truth

This week we look at the importance of truthfulness and how it is rooted in the character of God. We consider the consequences of lying, both for the person being deceived and the one telling the lie. The commandment against bearing false witness reflects God's truthfulness. We apply the ninth commandment by seeking and advocating for truth in all aspects of life. Living in truth reflects the character of God and provides an opportunity for the people of God to share the gospel.

March 12 Sermon: God Provides

I can remember the first time that I heard about someone that I know violating the Eighth Commandment. A friend of mine and I were playing outside, and he invited me in to hear a little bit of gossip. I guess I was violating the ninth commandment too. But anyway, he invited me in to hear this gossip regarding his older brother. Now, of course, my four or five-year-old ears wanted to hear something bad about what his brother has done. He was a couple of years older than us, and he didn't treat us nice all the time, so I wanted the dirt on this kid. I was excited. Well, when I told my friend that I wanted to hear about this, he let me know what he had done, and I learned about the great Eminem heist of Worthing South Dakota. It was a big deal. That's right. His older brother had taken the five-finger discount of a bag of Eminens at our little grocery store there in town.

March 5 Sermon: God is Pure

So, we arrive today at the seventh commandment. And unsurprisingly, this is the commandment that more people than any of the other commandments have given me a little ribbing about. When you see something coming up in the text, particularly on this topic, anything involving sexuality, you're wondering, how is that guy going to handle that? And for the record, this guy wonders the same thing. You end up thinking about it a lot. You go through it in your head, what do you want to say? It's a sensitive topic because it's something that is persistently in front of us in our culture. You can't avoid it. Our culture is obsessed with the topic of sex. To preach on it then requires that we have to find some balance. You don't want to be soft on sin. You don't want to sound permissive. Well, then you want to be straightforward, but you don't want to risk maybe sounding vulgar or too blunt. You want to be sure that people understand that there's grace and that there's forgiveness for all sin, and that includes sexual sin.

February 26 Sermon: God is Life

So, as we've been making our way through the Ten Commandments, we find ourselves now to the Sixth Commandment. Now, each of the commandments are very serious, very serious, because if we violate them, we are violating the commands of a holy God. We're acting in rebellion against Him. But as we come to the Six Commandment, there's almost a new gravity to it, isn't there? Because the first table of the law, the first four commandments are very much something that we don't physically see the results of our breaking them. As serious as it is, the most serious commandment is to only serve the Lord God. The first commandment. That is the most serious commandment. But if I don't do that, I'm not really seeing my disobedience and my rebellion in a way that manifests itself. And, even as we were in the first table of the law two weeks ago, and we had honor your father and your mother, definitely a command directed toward somebody. My lack of honor toward somebody is more an internal thing.

Honor: Exodus 20:1-12 | Authority, Obedience, and the Glory of God

Honor: Exodus 20:1-12 | Authority, Obedience, and the Glory of God

We often think of the fifth commandment—“Honor your father and your mother”—as one meant for children. But in this sermon from Exodus 20:12, Pastor Mark shows us that this command reaches further and deeper than we may realize. It’s not just for kids, and it’s not just about our behavior—it’s about the posture of our hearts.

This commandment bridges our duty to God with our duty to others. In a culture that often disregards respect and elevates self over all, we are reminded that honoring authority—whether parents, elders, employers, or civic leaders—is a reflection of our submission to God’s ultimate authority. And as always, the law points us to our need for grace. Every one of us has failed to honor others perfectly, but Christ has perfectly obeyed and poured out mercy on those who trust in Him.

When We Worship: Exodus 20:1-11 | Resting in the Work of Christ

When We Worship: Exodus 20:1-11 | Resting in the Work of Christ

In a culture driven by productivity and performance, the fourth commandment stands out as both a command and a gift. In this sermon from Exodus 20:8–11, Pastor Mark reflects on God’s call to Sabbath rest and how that rest finds its ultimate fulfillment in the finished work of Christ. The Sabbath is not merely a break from work—it is a day to worship, a day to rejoice in what God has done, and a weekly reminder that we are not defined by what we do, but by what has been done for us.

This message explores the shift from the seventh-day rest in the old covenant to the Lord’s Day in the new, where we begin our week resting in Christ's resurrection and then go forth to serve. Rather than working toward rest, Christians now work from rest—trusting in God’s providence, celebrating His grace, and finding true peace in His presence.

How We Talk About God: Exodus 20:7 | God Has Spoken—How Should We Speak of Him?

How seriously do we take the way we speak about God? The Third Commandment is about far more than avoiding a few specific words—it's about revering the holy name of the One who has spoken to us and called us His own.

In this sermon, Pastor Mark unpacks Exodus 20:1-7, showing us the depth of the Third Commandment. It’s not just about avoiding misuse of God’s name but also about how we live, speak, and teach in a way that reflects His truth and glory. Our speech matters because God’s name is holy, and He has spoken to us with power and grace.

How We Worship: Exodus 20:1–6 | The Golden Calf and the Human Heart

What does it mean to worship God in the way He desires?
In this sermon on the Second Commandment, Pastor Mark helps us understand the difference between who we worship and how we worship. Drawing from Exodus 20:1–6 and the story of the golden calf, he challenges us to consider the seriousness of approaching God on His terms, not our own. Whether we’re tempted to craft physical images or subtle mental ones, we’re reminded that God has revealed Himself in His Word—not in anything we create. Join us as we explore why biblical worship matters and how God graciously shows us the way.

Who We Worship: Exodus 20:1–3 | Worshiping the God Who Saves

The first commandment — You shall have no other gods before Me — often seems like the easiest to keep. But a closer look reveals just how central and convicting it really is.

In this sermon on Exodus 20:1–3, Pastor Mark unpacks the depth of this command by tracing its connection to the Exodus story, our modern struggle with identity and purpose, and the Westminster Shorter Catechism's call to glorify God and enjoy Him forever. We're reminded that the human heart is a “perpetual idol factory,” and that every other sin is, at its core, a failure to worship the one true God.

God Spoke: Exodus 20:1-2 | Hearing the Heart of God's Commands

When we think of the Ten Commandments, we often jump straight to the “do this, don’t do that” language. But before any command is given, God speaks as the Redeemer. In this sermon on Exodus 20:1–2, Pastor Mark helps us slow down and reflect on the foundational truth that God’s law is always given to a people He has already rescued.
