Christ: When Paul arrived in Corinth, he deliberately refused to rely upon superiority of speech or of wisdom (1 Cor. 2:1). Instead, he came proclaiming the testimony of God (v. 1), recognizing that the messenger must never overshadow the message. This is why Paul states, I determined to know nothing among you except Jesus Christ, and Him crucified¹ (v. 2). The focus on Christ crucified is especially significant because the cross appeared foolish and weak to the world (1 Cor. 1:18, 23). Yet through the cross God accomplished salvation. Jesus, the promised Messiah, willingly bore the penalty for sin to reconcile sinners to God (Isa. 53:5–6; 2 Cor. 5:21). The cross reveals both God's justice against sin and His love toward sinners (Rom. 3:25–26; 5:8). For Paul, the church's greatest need was not better philosophy, more impressive speakers, or superior rhetoric. Its greatest need was a deeper understanding of Jesus Christ and His finished work on the cross.²
Power: Paul reminds the Corinthians that he ministered among them in weakness and in fear and in much trembling (1 Cor. 2:3). Rather than presenting himself as strong and self-confident, he openly acknowledged his inadequacy. This was not a weakness to be hidden but a reality that highlighted God's power. Paul's preaching was not in persuasive words of wisdom, but in demonstration of the Spirit and of power (v. 4). While Paul used reason and persuasion elsewhere in his ministry (Acts 17:2–3), he understood that no amount of human eloquence can produce genuine faith. Only the Holy Spirit can open blind eyes, convict hearts, and bring spiritual life to those who are spiritually dead.3 Paul's purpose was clear, so that a believer’s faith would not rest on the wisdom of men, but on the power of God (v. 5). Faith built upon human personalities, human wisdom, emotional experiences, or worldly success will eventually fail. However, faith grounded in God's saving power revealed through the gospel endures because its foundation is Christ Himself, who is the same yesterday and today and forever (Heb. 13:8).
¹ Paul does not mean that he literally taught nothing except the crucifixion. Rather, Christ crucified functioned as the governing center of all his teaching. Every doctrine, command, promise, and exhortation finds its meaning in the person of Jesus Christ. See also Colossians 1:28, where Paul proclaims Christ as the focus of his ministry.
2 Therefore, faithful Christian ministry must continually point people back to Christ as the source of redemption, hope, and life. Ephesians 1:7, Colossians 1:13–14, 1 Peter 1:18–19, 1 Timothy 1:1, Colossians 1:27, 1 Peter 1:3, John 14:6, John 11:25, John 10:10, 1 John 5:11–12.
3 This is consistent with Paul's broader teaching regarding spiritual understanding. Apart from the work of the Holy Spirit, people do not receive the things of God (1 Cor. 2:14). Saving faith is ultimately the result of God's gracious work (Eph. 2:8–9).
