Part 5 of 12 | The Gospel Without An Edit Button: Sin, The Cross, The Resurrection, Repentance, & Grace
Key Scriptures
• Romans 1:16-25; 3:9-31; 5:6-11
• 1 Corinthians 15:1-8
"Now I make known to you, brothers and sisters, the gospel which I preached to you, which you also received, in which you also stand by which you also are saved, if you hold firmly to the word which I preached to you, unless you believed in vain. For I handed down to you as of first importance what I also received, that Christ died for our sins according to the Scriptures and that He was buried, and that He was raised on the third day according to the Scriptures and that He appeared to Cephas, then to the twelve. After that He appeared to more than five hundred brothers and sisters at one time, most of whom remain until now, but some have fallen asleep then He appeared to James, then to all the apostles and last of all, as to one untimely born, He appeared to me also."
• 2 Corinthians 5:14-21
"For the love of Christ controls us, having concluded this, that one died for all, therefore all died and He died for all, so that those who live would no longer live for themselves, but for Him who died and rose on their behalf. Therefore from now on we recognize no one by the flesh; even though we have known Christ by the flesh, yet now we know Him in this way no longer. Therefore if anyone is in Christ, this person is a new creation; the old things passed away; behold, new things have come. Now all these things are from God, who reconciled us to Himself through Christ and gave us the ministry of reconciliation namely, that God was in Christ reconciling the world to Himself, not counting their wrongdoings against them, and He has committed to us the word of reconciliation. Therefore, we are ambassadors for Christ, as though God were making an appeal through us; we beg you on behalf of Christ, be reconciled to God. He made Him who knew no sin to be sin in our behalf, so that we might become the righteousness of God in Him."
• Galatians 1:6-10; 2:15-21
"I am amazed that you are so quickly deserting Him who called you by the grace of Christ, for a different gospel, which is not just another account; but there are some who are disturbing you and want to distort the gospel of Christ. But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed! As we have said before, even now I say again: if anyone is preaching to you a gospel contrary to what you received, he is to be accursed! For am I now seeking the favor of people, or of God? Or am I striving to please people? If I were still trying to please people, I would not be a bond-servant of Christ."
“We are Jews by nature and not sinners from the Gentiles; nevertheless, knowing that a person is not justified by works of the Law but through faith in Christ Jesus, even we have believed in Christ Jesus, so that we may be justified by faith in Christ and not by works of the Law; since by works of the Law no flesh will be justified. But if, while seeking to be justified in Christ, we ourselves have also been found sinners, is Christ then a servant of sin? Far from it! For if I rebuild what I have once destroyed, I prove myself to be a wrongdoer. For through the Law I died to the Law, so that I might live for God. I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me. I do not nullify the grace of God, for if righteousness comes through the Law, then Christ died needlessly.”
• Ephesians 2:1-10
"And you were dead in your offenses and sins, in which you previously walked according to the course of this world, according to the prince of the power of the air, of the spirit that is now working in the sons of disobedience. Among them we too all previously lived in the lusts of our flesh, indulging the desires of the flesh and of the mind, and were by nature children of wrath, just as the rest. But God, being rich in mercy, because of His great love with which He loved us, even when we were dead in our wrongdoings, made us alive together with Christ (by grace you have been saved), and raised us up with Him, and seated us with Him in the heavenly places in Christ Jesus, so that in the ages to come He might show the boundless riches of His grace in kindness toward us in Christ Jesus. For by grace you have been saved through faith; and this is not of yourselves, it is the gift of God; not a result of works, so that no one may boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them."
• Mark 1:14-15
"Now after John was taken into custody, Jesus came into Galilee, preaching the gospel of God, and saying, “The time is fulfilled, and the kingdom of God has come near; repent and believe in the gospel.”
• Luke 24:44-49
"Now He said to them, “These are My words which I spoke to you while I was still with you, that all the things that are written about Me in the Law of Moses and the Prophets and the Psalms must be fulfilled.” Then He opened their minds to understand the Scriptures, and He said to them, “So it is written, that the Christ would suffer and rise from the dead on the third day, and that repentance for forgiveness of sins would be proclaimed in His name to all the nations, beginning from Jerusalem. You are witnesses of these things. And behold, I am sending the promise of My Father upon you; but you are to stay in the city until you are clothed with power from on high.”
Good News Has A Necessary Backdrop
The gospel means good news, but good news is understood only in relation to the crisis it resolves. If a person believes the human problem is low self-esteem, lack of education, political oppression, emotional pain, or social exclusion, Jesus may be presented mainly as therapist, teacher, liberator, or community builder. He cares about the whole person and His kingdom has profound implications for every dimension of life. Yet the apostolic gospel identifies a deeper problem beneath all others: humanity is alienated from the holy God by sin and lies under death.
Romans 3 refuses every claim of moral superiority. Jew and Gentile alike are under sin; no one is righteous by personal achievement; every mouth is stopped before God. Sin is not limited to unusually cruel acts. It is lawlessness, unbelief, disordered worship, failure to love God and neighbor, and falling short of God's glory. We sin because we are sinners, and our actions also deepen the slavery. This diagnosis wounds pride, but it creates the possibility of real hope. A shallow diagnosis can offer only a shallow cure.
Culture often redefines sin as authenticity, weakness as identity, and guilt as a feeling to be managed. The church is tempted to avoid the subject because it sounds negative. But concealing a fatal diagnosis is not kindness. The biblical doctrine of sin explains both why human beings retain astonishing dignity as God's image-bearers and why every person and institution is bent toward corruption. It guards against naive utopianism and cynical dehumanization at the same time.
The Holy Love Revealed At The Cross
At the cross, God does not choose between holiness and love. He reveals both. Romans 3 says that God set forth Christ so that He might be just and the justifier of the one who has faith in Jesus. Forgiveness is not God pretending evil does not matter. The Judge Himself provides the sacrifice through which guilt is dealt with and mercy is given without moral indifference.
Scripture uses several complementary pictures for Christ's work: sacrifice, redemption, reconciliation, victory, justification, and substitution. We should not flatten them into one metaphor, yet substitution stands near the heart of them.
Isaiah 53 anticipates the Servant wounded for transgressions. Jesus gives His life as a ransom for many. Paul says the sinless One was made sin for us so that in Him we might become God's righteousness. Peter says Christ bore our sins in His body on the tree. He does not become morally sinful; He stands in the place of His people and bears the judgment their sin deserves.
The cross therefore destroys boasting. We cannot save ourselves, contribute merit, or treat grace as divine assistance for basically good people. It also destroys despair.
The measure of God's willingness to save is not our emotional sense of worthiness but the gift of His Son. Romans 5 says that while we were enemies, we were reconciled to God through the death of His Son. Grace meets the guilty, not the deserving.
Raised For A New Creation
The gospel Paul received and delivered in 1 Corinthians 15 includes that Christ died for sins, was buried, was raised on the third day, and appeared. The resurrection is not an optional ending added to the "real" message of the cross. A dead savior cannot conquer death, vindicate His claims, or reign. The resurrection declares that the sacrifice was accepted, Jesus is Lord, death's dominion has been broken, and the promised new creation has begun in Him.
This keeps Christian hope from collapsing into moral improvement. Salvation is not merely becoming nicer while moving toward the grave. Believers are united to the risen Christ, receive the Spirit as a pledge, and await bodily resurrection. The gospel addresses guilt and corruption, soul and body, present obedience and future glory. It does not promise escape from creature-hood but the redemption of God's creation.
Apologetically, this historical center distinguishes Christianity from generic spirituality. The gospel is not true because it produces comforting feelings; its comfort rests on what God did. Christians should welcome examination of the resurrection claims while refusing a naturalistic rule that declares miracles impossible before evidence is considered. If God exists and created the universe, raising Jesus is not incoherent. The question is whether God acted and what evidence best explains the testimony.
Repent & Believe Is An Invitation, Not A Revision
Jesus entered Galilee proclaiming, "repent ye, and believe the gospel." Repentance is a Spirit-enabled change of mind and direction in which a sinner turns from self-rule and sin toward God. Faith is not mere agreement that religious facts exist; it is receiving and resting upon Christ. Repentance and faith are distinguishable but inseparable movements of conversion. We do not abandon sin in order to earn grace. Grace turns us toward the Savior and away from the rebellion that destroys us.
A message of affirmation without repentance cannot explain Jesus' preaching, the apostolic mission, or the transforming purpose of salvation. At the same time, a demand for moral reform without the finished work of Christ is not the gospel either. Legalism says, "Change so God will accept you." The gospel says, "In Christ, God justifies the ungodly who trust Him, and the grace that saves also trains them to renounce ungodliness." Works are not the root of justification; they are its fruit.
This distinction is pastorally vital. Sensitive believers may look inward, see imperfect repentance, and fear that Christ's work is insufficient. Presumptuous hearers may claim faith while protecting settled rebellion. Scripture directs both away from self-deception and toward Christ. The question is not whether repentance is flawless, but whether we are honestly turning to the Savior, bringing sin into the light, and submitting to His transforming grace.
"Another Gospel" Can Still Use Christian Words
Galatians 1 expresses apostolic astonishment that churches were turning to a different gospel, which Paul immediately says is not truly another good news at all. False teachers were not necessarily denying every Christian word. They were adding circumcision and law observance as necessary grounds of belonging, thereby corrupting justification by faith. Paul treats the distortion as spiritually deadly because changing the basis of acceptance changes the message itself.
Modern revisions take different forms. The prosperity message can turn Christ into a means of wealth and health. Moralistic religion can reduce the gospel to good behavior. Therapeutic religion can make personal wellness the highest good. Political religion can identify redemption with the triumph of a party or nation. Universalism can remove the necessity of repentant faith. Progressive revision can retain the vocabulary of Jesus while redefining sin according to cultural approval. Hyper-grace teaching can speak of forgiveness while dismissing holiness and discipline. Each error may preserve a Christian term while relocating the center.
The test is not whether a message uses the words love, grace, justice, kingdom, blessing, or Jesus. Ask: Who is Christ? What is the human problem? What happened at the cross and resurrection? How is a sinner made right with God? What response does God command? What kind of life does grace produce? A faithful gospel keeps God's holiness, human sin, Christ's sufficient work, justification by grace through faith, repentance, the Spirit's transformation, and future judgment in their biblical relationship.
Answering The Moral Objection To Judgment
People often ask, "How can a loving God judge?" The question deserves more than a slogan. Begin by acknowledging that judgment is frightening and that Christians do not stand outside its reach by moral superiority. Then ask whether a loving God could remain indifferent to abuse, exploitation, cruelty, deceit, and the desecration of His creatures. Our outrage at injustice assumes that evil deserves a truthful reckoning. A god who never judges may seem comforting to the comfortable but would offer no final justice to victims.
The deeper offense is often not that God judges spectacular evil, but that He claims authority to judge us. Scripture's standard is not comparison with worse people; it is God's holy character. The same God who judges has entered history to bear judgment for sinners. Hell is not evidence that the cross was unnecessary; the cross reveals how serious judgment is and how far divine love went to save. Christians should speak of this with gravity, never delighting in another person's peril.
When someone says, "I am a good person," do not rush to humiliate them. Explore the standard. Most people recognize they have failed even their own moral ideals, harmed others, and excused in themselves what they condemn elsewhere. Then explain that Christianity does not divide humanity into good people who need applause and bad people who need grace. It announces grace for guilty people who cannot justify themselves. That includes every Christian.
PASTORAL WARNING: If we remove sin to make the message less offensive, the cross becomes unintelligible. If we remove repentance to make grace less demanding, faith becomes empty agreement. If we remove resurrection to make Christianity more respectable, hope remains in the grave.
Sin Is More Than Broken Rules
Scripture describes sin through several related images: lawlessness, unbelief, idolatry, rebellion, impurity, debt, slavery, and falling short of God's glory. These images prevent a shallow account. Sin includes wrongful acts, but it also reaches desires, loyalties, habits, systems, and the heart's refusal to honor God as God (Romans 1:21).
A culture may recognize harm while rejecting holiness, or condemn selected injustices while enthroning autonomy. The biblical diagnosis is more searching because it measures humanity by the character and purpose of the Creator.
This doctrine should never produce smugness. Romans 3 gathers every group under sin so that every mouth is stopped. The defender of Christian morality stands among the guilty, not above them. We differ from the unbeliever not because our need was smaller but because mercy found us. When the church speaks of sin without grief, self-examination, and compassion, it contradicts the gospel's leveling force. Yet when it removes the diagnosis to appear welcoming, it withholds the truth that makes grace intelligible.
At The Cross, Justice & Mercy Meet
Romans 3:25-26 presents Christ as the atoning sacrifice through whom God demonstrates His righteousness so that He may be just and the justifier of the one who has faith in Jesus. Forgiveness is not divine indifference. God does not call evil imaginary, excuse oppression, or set aside holiness. In the cross, the Son willingly bears judgment as the covenant representative of His people. The Judge Himself provides the costly ground of pardon.
Biblical language about the cross is rich: sacrifice, ransom, reconciliation, victory, redemption, substitution, and covenant. These themes should not be made rivals. Christ bears sins, defeats hostile powers, purchases a people, reconciles enemies, and inaugurates a new covenant. Substitution remains central because victory over sin requires that guilt be answered, and reconciliation requires that enmity be removed. The cross reveals both the severity of our condition and the measureless love of God.
Grace Creates A New Standing & A New Life
Justification means God declares the ungodly righteous through faith because of Christ, not because moral improvement has earned acceptance. Adoption means those once alienated are welcomed as sons and daughters with access to the Father. Union with Christ means believers participate in the benefits of His death and resurrection. Sanctification means the Spirit progressively conforms them to His holiness. These truths distinguish salvation from self-repair while refusing a grace that leaves the person under sin's rule.
The order matters pastorally. We do not obey in order to persuade God to receive us; in Christ we obey because we have been received. At the same time, a profession that makes peace with unrepentant rebellion should not be comforted with fragments of justification detached from regeneration. Ephesians 2 holds the sequence together: saved by grace through faith, not by works, created in Christ Jesus for good works. Good works are not the root of salvation, but they are its appointed fruit.
Invitation, Assurance, & The Danger Of False Peace
The gospel invitation is sincerely offered to sinners: repent and believe, come to Christ, receive the living water, call upon the name of the Lord. No one must first become morally impressive. The warrant for coming is Christ's promise, not the quality of our remorse. Faith brings empty hands to a sufficient Savior. Repentance is the turning of the whole person from sin toward God, and even that turning is sustained by grace.
Pastoral seriousness refuses both needless doubt and careless assurance. Tender believers may stare at the weakness of their faith instead of the strength of Christ. They need His promises. Presumptuous hearers may point to a past prayer while resisting His lordship. They need His warnings. First John directs assurance toward the apostolic Christ, trust in His atoning work, growing obedience, love for believers, and the Spirit's witness. The purpose is not morbid introspection but a settled, fruitful confidence anchored outside ourselves.
Apologetics Practice: Explain The Gospel In Four Movements
Practice explaining the gospel through four movements: Creation, Fall, Redemption, and Restoration.
Creation explains that God made the world good and human beings in His image for His glory.
The Fall explains sin, guilt, corruption, alienation, and death.
Redemption centers on the incarnate Son's obedient life, atoning death, bodily resurrection, and gift of justification by grace through faith.
Restoration describes the Spirit's transforming work, the church's witness, Christ's return, resurrection, judgment, and new creation.
Give yourself three versions: a thirty-second summary, a three-minute explanation, and a longer conversation. Do not treat brevity as permission to omit the identity of Jesus or the call to respond. End with a genuine invitation: turn from self-rule, trust the risen Christ, and receive the mercy no one can earn. Then prepare to listen. Gospel proclamation is not a speech delivered at a target; it is witness offered to a person.
Reflection: Has the Gospel Searched Your Gospel?
1. Which part of the biblical diagnosis of sin are you most tempted to minimize?
2. How does the cross reveal God's justice and love without canceling either?
3. Why are both the death and bodily resurrection of Jesus essential to the gospel?
4. Do you tend toward legalism, cheap grace, therapeutic religion, political religion, or another practical distortion?
5. Can you explain repentance without making it a work that earns salvation?
6. When you discuss judgment, do people hear grief, humility, and the offer of mercy?
Conclusion: Do Not Improve The Message God Uses To Save
The gospel does not need our revisions. It needs truthful proclamation. Human sin is more serious than culture admits, divine holiness is more radiant than we imagine, Christ's sacrifice is more sufficient than our guilt, and resurrection hope is more concrete than vague spirituality. Grace is free to the receiver because it was infinitely costly to the Giver.
To defend this gospel is to refuse both harsh distortion and sentimental reduction. We announce judgment as those who deserved it, grace as those who received it, holiness as those being transformed, and hope as those whose Savior left the grave. We do not offer ourselves as the answer. We point to Christ.
Closing Prayer
Holy and merciful God, keep us from editing the gospel to protect our pride or gain approval. Show us the seriousness sin and the greater sufficiency of Christ. Thank You that Jesus bore judgment, rose bodily, and offers righteousness that we cannot earn. Grant us true repentance and living faith. Expose every false gospel we have believed or repeated. Teach us to speak of sin with tears, grace with wonder, holiness with humility, and resurrection with confidence. Make us faithful to the message that saves.
In Jesus Name, Amen.
Week 6 Preview
Next week we will turn from what we defend to how we defend it. Scripture commands both readiness and gentleness. We will examine the difference between boldness and belligerence, the discipline of listening, the danger of online outrage, the role of questions, and the clean conscience that gives Christian witness moral weight.
