By the Cross's Light - Contemporary Worship

The Scriptures call believers to live as salt and light: adding flavor to a dull world and shining the truth of Christ so others may see good works and glorify the Father. The gospel passage frames Christian vocation as visible fidelity—a city on a hill and a lamp on a stand—so faith manifests in concrete acts that draw attention not to self but to God. The cross stands at the center of that vision; Christ crucified becomes the interpretive lens that illumines sin, divine character, moral law, and human suffering. Saint Paul’s insistence on knowing nothing “except Jesus Christ and him crucified” functions not as narrowness but as a proposal: let the cross speak into every topic and reorder understanding by its light.

The cross exposes the depth of sin and secures forgiveness by the costly sacrifice of God’s Son, thereby transforming how the law appears. Law no longer arrives merely as accusation or restriction; viewed through the cross it shapes discipleship—self-denial, sacrificial love, and faithfulness modeled on Christ’s own surrender. The sixth commandment, for example, becomes a picture of the bridegroom’s love for the church rather than a burdensome prohibition, inviting spouses to imitate Christ’s self-giving. Suffering, likewise, receives a new grammar beneath the cross: it does not prove God’s callousness. Instead, the cross rules out cruel explanations and opens possibilities—strengthening faith, stripping idols, shaping Christlikeness, and pointing to the hope of resurrection.

The narrative affirms that God sovereignly redeems evil, using even intended harm to accomplish good, as on Good Friday where apparent defeat became the means of salvation. Worship life, creedal confession, and the Lord’s Supper center this truth: the church remembers the crucified Christ who gives forgiveness, forms moral vision, and grants endurance. The call to be salt and light therefore flows from the cross; believers bear witness in everyday choices, in the joyful obedience of the law reframed by grace, and in patient trust when pain presses in. May the cross continue to illuminate conscience, strengthen faith, and direct service so that all actions point others toward the glory of God.

Key Takeaways

• 1. Called to be salt and light Believers participate in God’s work by making tangible differences where they live—adding moral flavor and clarity to ordinary settings so others can see God’s goodness. This vocation centers on deeds that reflect Christ, not on visibility for its own sake; faithful small acts compound into public witness. Such presence resists both hiddenness and spectacle, aiming instead to orient hearts toward the Father. [12:45]
• 2. Cross illumines every truth The crucified Christ functions as the interpretive lens for Scripture and life, so every doctrine and dilemma gains clarity when held up to the cross. Rather than treating the cross as one theme among many, the cross reorders priorities and corrects misunderstandings about sin, grace, and God’s will. This orientation prevents theological compartmentalizing and fosters unity between belief and daily practice. [21:37]
• 3. Law seen through the cross God’s commands become invitations to mirror Christ’s self-giving when viewed through the crucifixion, transforming duty into delighted obedience. Moral demands cease to feel like external shackles and instead shape a life formed by sacrificial love—first received, then returned to God and neighbor. This reframing makes moral fidelity an act of worship rather than merely legal compliance. [26:04]
• 4. Suffering rests under God’s purposes Pain and trial do not expose divine indifference; the cross demonstrates that God uses apparent evil to bring about ultimate good. Suffering can strengthen prayer, remove idols, shape Christlike endurance, and heighten longing for the world to come, even when specific reasons remain hidden. Trust grows by remembering that God foresees and fashions suffering into redemptive outcomes. [30:33]

Bible reading
Matthew 5:13-20 (ESV)
“You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people's feet. You are the light of the world. A city set on a hill cannot be hidden. Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven. Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven. For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.”

1 Corinthians 2:2 (ESV)
For I decided to know nothing among you except Jesus Christ and him crucified.

Romans 8:32 (ESV)
He who did not spare his own Son but gave him up for us all, how will he not also with him graciously give us all things?

Observation questions

1. In the Gospel reading, what two things does Jesus say his followers are, and what is the purpose of each?
2. What does Paul say he decided to focus on above all else when he was among the Corinthians? [22:48]
3. According to the message, how does viewing the Sixth Commandment through the cross change its meaning from a burden to a source of joy? [27:22]
4. What are some of the wrong answers about suffering that the cross eliminates? [29:43]

Interpretation questions

1. How does the concept of being "salt" and "light" move beyond mere personal morality to a public, tangible witness that points others to God?
2. If Paul discussed many topics like marriage and spiritual gifts, what did he mean by saying he would only speak of "Jesus Christ and him crucified"? How does the cross become a lens for every issue? [22:48]
3. The law is described as being "cross-shaped." What does it mean for a Christian's obedience to be shaped by self-denial and sacrificial love, rather than just rule-following? [26:04]
4. The cross demonstrates that God can use intended evil for ultimate good. How does this truth provide a framework for understanding our own suffering, even when the specific reason is hidden? [31:48]

Application questions

1. Salt is often invisible but makes a tangible difference. What is one "invisible" act of love or integrity you can do this week that will add Christ's flavor to your workplace, school, or home?
2. A light is meant to be seen. Is your life currently more like a lamp hidden under a basket or placed on a stand? What is one area where you feel called to let your good works shine more openly for God's glory?
3. The cross transforms how we see God's commands from burdens to opportunities. Which of God's commands feels most like a burden or restriction to you right now? How might praying for God to help you see it through the lens of Christ's sacrificial love change your perspective? [26:04]
4. When a difficult situation arises, what is your first instinct—to ask "Why is this happening to me?" or to remember that God can use even intended evil for good? [31:48]
5. The Sixth Commandment becomes a picture of Christ's love for the church. For those who are married, what is one practical way you can imitate Jesus’ self-giving love for your spouse this week? For everyone, how can this same principle of sacrificial love shape your other relationships? [27:22]
6. Suffering can be used to strip away idols. What is something you rely on for comfort, security, or identity more than you rely on God? How might trusting in God's love, proven at the cross, free you from that dependency? [30:33]
7. The Lord's Supper is a time to remember the crucified Christ. How can regularly receiving this gift strengthen you to be salt and light in your everyday life?
