Introduction to 1 Corinthians

The City of Corinth and the Relevance of Paul’s Letter
Corinth was an influential city in the first century, known for its wealth, commerce, and widespread immorality. Yet, even in this challenging environment, the gospel of Jesus Christ took root and the Lord's church was established. Paul’s first letter to the Corinthians, written around the 50s AD, addresses real-life issues faced by this congregation. These issues, from divisions to moral challenges, remain highly relevant to churches today. In 1 Corinthians 1:1–3, Paul greets the church of God which is at Corinth. This greeting emphasizes the importance of belonging to the body of Christ. The concept of a Christian who is not part of the church is foreign to scripture. Just as Acts 2 shows that those who believed and obeyed the gospel were added to the church, so it remains today: the church is not optional, but essential to salvation and spiritual growth.

The Eternal Purpose and Sanctification of the Church
Paul begins by highlighting that the church is God’s, not man’s. In Ephesians 3:10–11, we learn that the church was part of God’s eternal plan, designed to reveal His manifold wisdom. It was not an afterthought or a temporary measure. The church is the body of Christ, and its members are sanctified in Christ Jesus (1 Corinthians 1:2). Sanctification means being set apart for God’s purposes. Paul reminds the Corinthians in 1 Corinthians 6:11 that they were once fornicators, idolaters, drunkards, and more, but they were washed, sanctified, and justified through Christ. Sanctification is inseparable from being in Christ’s church. Outside of the church, there is no sanctification.

The Call to Be Saints Through the Gospel
The Corinthians were called to be saints, and so are all who obey the gospel. This calling is not mystical or individualistic; it comes through the message of the gospel itself. In 1 Corinthians 15:1–4, Paul summarizes this gospel: that Christ died for our sins, was buried, and rose again according to the Scriptures. 2 Thessalonians 2:13–14 confirms that we are called to salvation through the gospel. The title “saint” does not describe a special class of Christians but all faithful believers. Saints, disciples, and Christians are synonymous terms in scripture. This calling applies to all who call on the name of Jesus Christ our Lord in every place, affirming the unity of believers everywhere.

Grace and Spiritual Enrichment
Paul expresses gratitude for the grace of God given to the Corinthians through Christ (1 Corinthians 1:4–7). Grace is God’s unmerited favor, fully demonstrated in the cross of Christ. The Corinthians were enriched in speech, knowledge, and spiritual gifts. These gifts were given in the first century to confirm the truth of the gospel before the New Testament was fully written (Hebrews 2:3–4). Paul later explains in 1 Corinthians 13 that such gifts were temporary, serving like scaffolding during the construction of a building. Once the gospel message was complete and confirmed, these miraculous gifts were no longer needed. Today, we are enriched through the completed Word of God, which equips us for every good work (2 Timothy 3:16–17).

Eagerly Waiting for Christ
Paul commends the Corinthians for eagerly waiting for the revelation of our Lord Jesus Christ (1 Corinthians 1:7). Every Christian should share this longing for Christ’s return. However, this expectation must be grounded in truth. Jesus taught in Matthew 24 that no one knows the day or hour of His coming. Our task is not to speculate about the end but to remain faithful and ready. Paul reassures the Corinthians that Christ will confirm you to the end, that you may be blameless (1 Corinthians 1:8). This is not a guarantee apart from faithfulness. Revelation 2:10 urges believers to be faithful until death to receive the crown of life. Even Paul recognized the need for discipline and perseverance, lest he be disqualified (1 Corinthians 9:27).

God’s Faithfulness and Our Assurance
In verse 9, Paul assures the church that God is faithful. The same God who called them into the fellowship of His Son will not fail to keep His promises. Our salvation is secure as long as we remain steadfast in Christ. Satan cannot forcibly remove us from God’s hand, but we must not abandon the faith. God’s faithfulness should fill us with confidence and motivate us to live faithfully, knowing that our labor in the Lord is never in vain.
