The Ten Commandments: Ancient Law, Timeless Wisdom

The Ten Commandments were given to Moses on Mount Sinai (Exodus 20) roughly 3,500 years ago. And yet, every single one of them is as relevant today as the day it was written — because they’re built on unchanging truths about God and human nature.

Before diving in, we need to understand why God gave the Law. It wasn’t to give Israel a way to earn salvation — people have always been saved by faith (Romans 4). The Law serves three purposes:

To reveal God’s character — the Law shows us what God values: holiness, truth, justice, life.
To expose our sin — “through the law comes knowledge of sin” (Romans 3:20). The Commandments function like a mirror.
To point us to Christ — Galatians 3:24 says the Law was “our guardian until Christ came.” Every place the Law shows us where we’ve fallen short points us to our need for a Savior.

Commandment 1: No Other Gods

“You shall have no other gods before me.” (Exodus 20:3)

This one sounds easy — you probably don’t worship Zeus or Baal. But the principle runs deeper: anything that functionally takes God’s place in your heart is a god. Your phone, your reputation, your relationship, your appearance, your grades — any of these can become an idol when they take priority over your relationship with God.

Colossians 3:5 calls covetousness “idolatry.” The thing you crave most, the thing you’d be most devastated to lose — that’s worth examining.

Commandment 2: No Idols

“You shall not make for yourself a carved image…” (Exodus 20:4)

Related to the first, this commandment guards against reducing God to something you can control or shape. We don’t carve physical idols, but we’re experts at creating mental ones — a version of God designed to approve our existing choices, never challenge us, and be available on our schedule.

The real God will not be managed. He’s not a genie in a lamp.

Commandment 3: Don’t Misuse God’s Name

“You shall not take the name of the LORD your God in vain.” (Exodus 20:7)

This isn’t just about not saying “OMG.” It’s about not claiming God’s name without reflecting His character. Calling yourself a Christian while consistently behaving in ways that dishonor God is taking His name in vain.

Leviticus 19:12 extends this to false oaths. James 5:12: “Let your yes be yes and your no be no.” Integrity of word is part of honoring God’s name.

Commandment 4: Remember the Sabbath

“Remember the Sabbath day, to keep it holy.” (Exodus 20:8)

God built rest into the rhythm of creation (Genesis 2:2–3). The Sabbath commandment insists on regular, intentional stopping. We are not machines. Productivity is not the measure of your worth.

For Christians, the Sabbath principle applies in new covenant terms — Hebrews 4 speaks of entering “God’s rest” through faith in Christ. But the practical wisdom remains: human beings need regular rhythms of rest, worship, and disengagement from work.

Commandment 5: Honor Your Parents

“Honor your father and your mother.” (Exodus 20:12)

This is the first commandment with a promise attached: “that your days may be long in the land.” It’s the hinge between the God-focused first four commandments and the people-focused last six.

Honoring parents doesn’t require agreeing with everything they say. It means treating them with respect and gratitude, obeying them in lawful things (Ephesians 6:1–3), and not despising them even when you disagree.

This is often the hardest commandment for teenagers — and the one that shapes you most during these years. How you handle authority at home is how you’ll handle it everywhere else.

Commandment 6: Do Not Murder

“You shall not murder.” (Exodus 20:13)

This protects the sanctity of human life — every person is made in God’s image (Genesis 9:6) and therefore precious.

Jesus extends this in Matthew 5:21–22: unrighteous anger and contempt for others is murder in the heart. 1 John 3:15 confirms: “Everyone who hates his brother is a murderer.” The root of murder is devaluing human beings. Check your anger and the language you use when you’re furious at someone.

Commandment 7: Do Not Commit Adultery

“You shall not commit adultery.” (Exodus 20:14)

This protects the covenant of marriage — one of God’s most important institutions. And again, Jesus deepens the application: lust in the heart violates this commandment (Matthew 5:28).

In a hyper-sexualized culture, this commandment is routinely mocked. But the relational and psychological damage caused by sexual unfaithfulness is well-documented. God’s design protects people.

Commandment 8: Do Not Steal

“You shall not steal.” (Exodus 20:15)

Stealing isn’t just shoplifting. It’s copying homework and presenting it as yours. It’s taking credit for others’ work. It’s being paid for work you didn’t do. It’s time theft — being paid for hours you didn’t put in.

The positive counterpart: Ephesians 4:28 — “Let the thief no longer steal, but rather let him labor, doing honest work with his own hands, so that he may have something to share with anyone in need.”

Commandment 9: Do Not Bear False Witness

“You shall not bear false witness against your neighbor.” (Exodus 20:16)

This covers perjury in courts and all forms of lying and dishonesty in relationships. Proverbs 6:16–19 lists “a lying tongue” and “a false witness” among the things God hates most.

Why? Because God is truth (John 14:6) and the devil is “the father of lies” (John 8:44). Every lie we tell aligns us, at that moment, with evil rather than God.

Commandment 10: Do Not Covet

“You shall not covet…” (Exodus 20:17)

This is the commandment that lives entirely in the mind. You can covet without doing anything visible. And Paul says this commandment is what made him aware of the depth of sin in himself (Romans 7:7–8).

Contentment is the opposite of coveting — and it’s one of the most countercultural stances a Christian can take. Philippians 4:11: “I have learned, in whatever situation I am, to be content.” Not easy. But learned.

The Law and Grace Together

Understanding the Ten Commandments as a Christian means holding two things together:

We are not under the Law for salvation. Jesus fulfilled the Law perfectly on our behalf. We are saved by grace through faith, not by keeping the commandments (Galatians 3:13, Romans 8:3–4).
The Law still teaches us. These commandments reveal God’s character and show us how to live in ways that honor Him and love others well. The goal isn’t rule-following — it’s becoming the kind of people these rules describe.

Discussion questions:

Which commandment is hardest for you in your current season of life?
How does understanding Jesus as the fulfillment of the Law change how you approach the commandments?
Where do you see idolatry showing up in modern culture — and in your own life?

Key verse: “And he said to him, ‘You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself. On these two commandments depend all the Law and the Prophets.’” — Matthew 22:37–40
