Most conservative evangelical scholars and churches hold that the author of 1 Corinthians — and therefore of 1 Corinthians 15:55–57 — is the Apostle Paul. Below is a summary of who Paul was, why evangelicals accept his authorship of this letter, and how those verses are typically understood and applied from an evangelical perspective.

Who Paul was (evangelical summary)
– Personal background: Born Saul of Tarsus (a Roman citizen), educated as a Pharisee under Gamaliel, zealous for the Jewish law before his conversion (Acts 22:3; Philippians 3:5–6).
– Conversion and call: He was dramatically converted on the Damascus road (Acts 9), called to be an apostle to the Gentiles, and spent the rest of his life planting churches and writing letters that shaped early Christian theology.
– Ministry context: Paul undertook several missionary journeys across the Roman world, founded the church at Corinth, and wrote many of the New Testament epistles. He is central to the New Testament’s exposition of the gospel (justification by faith, union with Christ, the resurrection, etc.).
– Dating: 1 Corinthians is usually dated to the mid‑50s AD (around AD 53–55), written from Ephesus to the church in Corinth.

Why evangelicals attribute 1 Corinthians to Paul
– Internal claim: The letter begins with an explicit claim to be from Paul (“Paul, called to be an apostle of Christ Jesus…” — 1 Cor 1:1).
– Early testimony: The early church fathers (e.g., Clement of Rome, Irenaeus) recognized Paul’s letters as authoritative.
– Style and theology: The vocabulary, theological themes (gospel, justification, resurrection, Christian living), and pastoral concerns are consistent with Paul’s other undisputed letters.
– Scholarly consensus among evangelical commentators: 1 Corinthians is treated as an authentic Pauline epistle by the vast majority of evangelical scholars.

What 1 Corinthians 15:55–57 says (NIV wording for reference)
“O death, where is your sting?
O grave, where is your victory?”
The sting of death is sin, and the power of sin is the law.
But thanks be to God! He gives us the victory through our Lord Jesus Christ.

Evangelical reading and application of these verses
– Context: 1 Corinthians 15 argues for the reality and centrality of Christ’s bodily resurrection and the future bodily resurrection of believers. Paul is answering theological confusion in Corinth about resurrection (some denied it or misunderstood it).
– Meaning: “Death” and “Hades/Grave” are pictured as defeated. The “sting of death” is identified with sin, and the “power of sin” (linked to the law) has been overcome in Christ. God gives believers final victory — not through human effort, but through Jesus’ resurrection and Christ’s lordship.
– Theological significance:
– The passage affirms the gospel’s core claim: Christ’s resurrection defeats death and secures believers’ hope (1 Cor 15:14, 20–22).
– It ties together sin, law, Jesus’ victory, and eschatological hope (resurrection at Christ’s return).
– It provides comfort about death and assurance of resurrection life for those in Christ.
– Pastoral and practical implications: Evangelicals draw comfort and boldness from these verses for grieving believers, use them to encourage holy living (since resurrection reality motivates Christian ethics), and ground missionary urgency in the victory of the gospel.

Short summary
From an evangelical perspective, the most likely author of 1 Corinthians 15:55–57 is the Apostle Paul. The verses reflect Paul’s core gospel conviction: Christ’s resurrection decisively defeats sin and death and gives believers a living hope and final victory through Jesus Christ.
