Clarity: How Much Influence Should the Bible Have on Morality?

Part of the Clarity Series: Building a Christian Worldview

How much influence should the Bible have on our morality?

This is more than an abstract question—it shapes how we live every day. Whether we’re making personal choices, engaging in culture, or raising children, our view of right and wrong matters deeply.

In Clarity, we’re exploring key topics that shape our worldview. We’ve considered spiritual warfare, the trustworthiness of the Bible, faith and science, political identity, and the End Times. Now we turn to morality—and how Scripture forms it.

This is what I want you to remember: The Bible shapes the beliefs and behaviors of God’s people as we live as salt and light in the world.

The Lens of Our Worldview

Imagine trying to live out every command in the Bible for a year. That’s exactly what author A.J. Jacobs attempted in The Year of Living Biblically. In a TED Talk, he shared three key takeaways: following rules reshaped his behavior and mindset, sacredness matters, and—perhaps most notably—we all pick and choose the rules we follow.

Jacobs, an agnostic, made value judgments about which biblical commands seemed helpful or harmful. But that raises a deeper question: Who gets to define what’s right and wrong?

Across cultures and religions, morality exists. But a Christian worldview begins with a foundational claim: morality flows from God, our Creator. Romans 2:14–16 reveals that even those without the Law have a moral compass—because all humans are made in God’s image. We were created to reflect His character.

If that’s true, why don’t we all share the same moral convictions? The answer is found in the story the Bible tells.

The Bible’s Story: Our Moral Foundation

In the beginning, Adam and Eve were created to walk with God and learn from Him what is good. But in Genesis 3, they chose to define good and evil for themselves. That rebellion has echoed through human history ever since.

Still, God didn’t abandon His plan. He called Abraham and formed Israel to be a holy nation and a kingdom of priests (Exodus 19:5–6). They were to reflect His holiness and justice through the Law. Yet Israel, like humanity at large, often failed—choosing conformity to the world over obedience to God.

Through the prophet Isaiah, God declared Israel would be a “light to the nations” (Isaiah 42:6). That calling was ultimately fulfilled in Jesus, who said, “I am the light of the world” (John 8:12). And now, Jesus commissions His followers to carry that light, to be “the salt of the earth” and “the light of the world” (Matthew 5:13–16).

This is where our morality matters most: we are called to embody God’s character so that the world might see what love and truth look like.

Biblical Morality Begins with Love

Morality isn’t about legalism—it’s about love. When asked to name the greatest commandment, Jesus responded by quoting Deuteronomy 6 and Leviticus 19: “Love the Lord your God with all your heart… and love your neighbor as yourself” (Mark 12:29–31). The Ten Commandments reflect this: the first four teach us how to love God; the last six show us how to love people.

Love is more than a feeling. It’s sacrificial, intentional, and deeply rooted in action. Jesus showed us what this love looks like by washing feet, healing the broken, and dying on the cross (John 13:34–35). Paul echoed this call in Ephesians 5:1–21, urging us to walk in love, truth, and wisdom—to live lives that reflect the light of Christ.

The Bible’s Role in Shaping Morality

So how much influence should the Bible have on our morality? For followers of Jesus, it’s not just an influence—it’s the foundation. God’s Word reveals His will and character, forming our hearts and habits as we study, worship, and obey.

That doesn’t mean quoting Scripture will always convince others. Many reject the Bible’s authority. But we still influence the world—not by forcing moral codes, but by faithfully living as God’s people. That’s how the early church transformed the Roman Empire, and that’s how we can live as a faithful witness today.

Living the Truth: A Challenge

This week, read Ephesians 5:1–21.

Ask God to reveal any area where your life isn’t aligned with His love and truth. Then, choose one practical way to show sacrificial love to someone around you. Let your morality shine as a reflection of God’s light in the world.

Tying It All Together

This Clarity series helps us build a lens through which to view life.

• Spiritual warfare taught us to depend on God’s power.

• The Bible gave us a trustworthy source of truth.

• Science and faith reminded us that reason and revelation work together.

• Politics revealed our identity as citizens of God’s Kingdom.

• The End Times called us to live with purpose.

• And now, morality anchors us in love and holiness, pointing us toward the kind of life that reflects Jesus in a dark world.

Closing Prayer

• Thank God for the wisdom and truth found in His Word.

• Confess where your morality has been shaped more by culture than by Scripture.

• Ask God to help you live as salt and light, a faithful witness of His love and truth.
