What Then Must We Do?
Transforming Daily Life Through Authentic Fruits of Repentance
Sermon Summary
This sermon addresses the critical disconnect between verbal profession and practical Christian living. Grounded in Luke 3, it highlights John the Baptist's confrontation of religious presumption and his call for tangible fruits of repentance. The passage teaches that authentic spiritual turning manifests in compassionate sharing, vocational honesty, and contentment, leading believers to live transformed lives that reflect the righteousness of Jesus Christ.
Introduction
In our modern culture, it is remarkably easy to confuse religious sentiment with spiritual reality. We attend church services, learn biblical vocabulary, and align ourselves with faithful traditions, yet often leave our everyday habits entirely untouched. When John the Baptist emerged from the Judean wilderness, his piercing ministry shattered all human complacency. He confronted crowds who assumed that their lineage and religious identity guaranteed divine favour. Standing on the banks of the Jordan River, John announced that God demands more than emotional remorse or institutional belonging. True spiritual awakening drives a person to ask the urgent question: What then must we do? This question bridges the gap between hearing God's Word and obeying it. It transforms vague spiritual desires into practical obedience in our homes, workplaces, and communities.
Main Scripture
Luke 3:7-14
He said therefore to the multitudes who went out to be baptized by him, “ You offspring of vipers, who warned you to flee from the wrath to come? Therefore produce fruits worthy of repentance, and don’ t begin to say among yourselves, ‘ We have Abraham for our father; ’ for I tell you that God is able to raise up children to Abraham from these stones! Even now the ax also lies at the root of the trees. Every tree therefore that doesn’ t produce good fruit is cut down and thrown into the fire.” The multitudes asked him, “ What then must we do? ” He answered them, “ He who has two coats, let him give to him who has none. He who has food, let him do likewise.” Tax collectors also came to be baptized, and they said to him, “ Teacher, what must we do? ” He said to them, “ Collect no more than that which is appointed to you.” Soldiers also asked him, saying, “ What about us? What must we do? ” He said to them, “Extort from no one by violence, neither accuse anyone wrongfully. Be content with your wages.”
Luke 3:7-14 serves as the cornerstone of this message because it defines biblical repentance in concrete, ethical terms. In this passage, John the Baptist strips away ethnic and religious pride, warning that divine judgment is imminent for those whose lives produce no righteous fruit. When three distinct groups—the general crowds, tax collectors, and soldiers—ask him how they should respond, John does not command them to retreat into ascetic isolation or adopt complex religious rituals. Instead, he directs them back into their ordinary daily callings with transformed hearts. He demands active generosity toward the poor, uncompromised honesty in financial matters, and the rejection of extortion and greed. This passage reveals that true repentance is known by its practical fruits.
Main Sermon Points
1. Abandon Religious Presumption and Empty Rituals
Therefore produce fruits worthy of repentance, and don’ t begin to say among yourselves, ‘ We have Abraham for our father; ’ for I tell you that God is able to raise up children to Abraham from these stones!
John forcefully warns the crowds against relying on their heritage as descendants of Abraham. Belonging to a covenant community or inheriting a religious legacy cannot substitute for a personal, active turn from sin to righteousness.
Jesus echoes this truth by declaring that not everyone who calls Him Lord will enter the kingdom of heaven, but only those who actively do the will of the Father.
In ancient Israel, descent from Abraham was widely regarded as a spiritual guarantee of salvation. John shatters this presumption by stating that God can raise up children to Abraham from lifeless desert stones. External privilege without internal transformation is spiritually worthless before a holy God.
Believers must audit their lives to ensure they are not relying on past spiritual experiences, family church attendance, or outward religious routines. Examine your heart today and confess any hidden reliance on ritual, turning wholeheartedly to God with sincere repentance.
Quick Insights
- Spiritual heritage can never replace personal obedience to God.
- God seeks living fruit in our actions rather than traditional titles on our lips.
- True repentance begins when we stop making excuses for ongoing sin.
2. Demonstrate Authentic Love Through Radical Generosity
The multitudes asked him, “ What then must we do? ” He answered them, “ He who has two coats, let him give to him who has none. He who has food, let him do likewise.”
When the crowds ask how to manifest genuine repentance, John immediately points to basic human need. He commands those with extra clothing and food to share freely with those who lack basic necessities.
John the Apostle similarly teaches that if anyone has world goods and sees a brother in need yet closes his heart, the love of God does not abide in him.
Notice that John does not ask the crowd to perform extraordinary or heroic sacrifices, but to exercise basic, practical mercy. A heart truly turned toward God becomes open-handed toward neighbor, recognizing that material blessings are gifts to be shared rather than hoarded.
Look around your home, workplace, and neighborhood for practical opportunities to meet physical needs. Set aside clothing, extra food, or financial resources this week to directly bless a struggling family or community member in need.
Quick Insights
- A heart transformed by God naturally opens its hands to others.
- Generosity converts abstract faith into visible christian love.
- True repentance turns personal surplus into neighborly care.
3. Practice Daily Integrity in Your Calling
Tax collectors also came to be baptized, and they said to him, “ Teacher, what must we do? ” He said to them, “ Collect no more than that which is appointed to you.” Soldiers also asked him, saying, “ What about us? What must we do? ” He said to them, “Extort from no one by violence, neither accuse anyone wrongfully. Be content with your wages.”
John instructs corrupt tax collectors and soldiers not to abandon their vocations, but to perform their duties with absolute honesty, justice, and contentment, refraining from extortion and false accusations.
Paul instructs believers to work wholeheartedly as unto the Lord, keeping their conduct pure and honourable in every vocational environment.
Tax collectors were despised in Judea for taking excess money for personal profit, while soldiers frequently used force to intimidate citizens. John’s message does not require them to leave secular society, but to sanctify their daily work through ethical integrity, fairness, and contentment.
Refuse to participate in workplace dishonesty, bribery, or unfair advantage. Whether serving in business, government, education, or manual labor, conduct every financial transaction and professional duty with uncompromised honesty as a witness for Christ.
Quick Insights
- Your workplace is the primary arena where your repentance is tested.
- Contentment protects believers from the temptation of dishonest gain.
- Godly integrity in daily business brings honour to the gospel.
Bottom Line
Genuine biblical repentance is never merely emotional or ritualistic; it is an active turn from sin that produces observable fruits of generosity, fairness, and moral integrity in everyday life.
Memorable Quote
Genuine repentance is not measured by the tears we shed at an altar, but by the integrity and generosity we display in our daily lives.
Theological Point
The doctrine of evangelical repentance (metanoia) involves a fundamental mind transformation wrought by the Holy Spirit, which inevitably manifests in outward moral alignment with God's law and practical love for one's neighbour.
Prayer Guide
- Pray for a heart that turns away from self-reliance and religious pride.
- Ask God to open your eyes to the physical needs of people in your immediate community.
- Seek God's help to maintain uncompromised honesty and fairness in your daily work.
- Thank God for sending Jesus Christ to forgive our sins and transform our hearts.
Responding to God’s Word
When we confront the message of John the Baptist and ask, What Then Must We Do?, we are drawn to the reality that we cannot produce righteous fruit in our own strength. John prepared the way, but pointed beyond himself to Jesus Christ, the One who baptizes with the Holy Spirit and with fire. Our call to repentance is ultimately a call to come to Jesus, who lived the perfect life of love, righteousness, and integrity on our behalf. He bore our sins upon the cross so that we might be forgiven, cleansed, and empowered by His Spirit. True obedience flows from a heart redeemed by His grace. As you return to your family, your business, your school, and your community, resolve to walk in the light of His truth. Turn away from religious complacency, practice practical generosity, uphold unbending integrity in your daily work, and let your light so shine before others that they may see your good works and glorify your Father in heaven.
