The author of ‘1 Corinthians 2:14’ is the Apostle Paul, a key figure in early Christianity and one of the most influential writers of the New Testament. Paul is widely accepted among evangelical Christians as the author of the letter to the Corinthians, which addresses various issues facing the church in Corinth.

### Background on Paul
1. **Background and Conversion**: Originally known as Saul of Tarsus, Paul was a Pharisee who persecuted early Christians. His dramatic conversion on the road to Damascus, as described in Acts 9, transformed him into a devoted follower of Jesus Christ. After his conversion, Paul became one of the foremost apostles and evangelists, spreading the Gospel throughout the Roman Empire.

2. **Missionary Work**: Paul embarked on several missionary journeys, establishing churches in various cities, including Corinth. His experiences and teachings during these missions form the basis for many of his epistles, addressing doctrinal and practical issues in the church.

3. **Authorship of the Letter**: ‘1 Corinthians’ is a letter written to the church in Corinth, addressing issues of division, immorality, and questions about spiritual gifts and resurrection. Paul wrote this letter while he was in Ephesus, around AD 55, responding to reports and inquiries from the Corinthian church.

### Context of 1 Corinthians 2:14
In 1 Corinthians 2:14, Paul writes:

> “The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit.” (NIV)

This verse underscores the importance of the Holy Spirit in understanding spiritual truths. Paul contrasts the natural person, who lacks the Spirit and thus cannot comprehend spiritual realities, with the spiritual person, who discerns and understands these truths through the Holy Spirit.

### Evangelical Perspective
1. **Authority of Scripture**: Evangelical Christians view Paul’s writings as authoritative scripture inspired by the Holy Spirit. This belief emphasizes that messages like the one in 1 Corinthians 2:14 are relevant for believers today.

2. **Role of the Holy Spirit**: The verse highlights a central tenet in evangelical theology: the necessity of the Holy Spirit for spiritual understanding. Evangelicals believe that spiritual discernment and comprehension of God’s truth are reliant on the work of the Holy Spirit in a believer’s life.

3. **Application to Life**: Many evangelicals see Paul’s teachings as applicable to contemporary issues, reinforcing the idea that without spiritual awakening through the Holy Spirit, individuals will struggle to grasp the significance of God’s message.

In summary, from an evangelical perspective, Paul is an essential figure whose authorship of 1 Corinthians profoundly impacts Christian theology, particularly regarding the relationship between the Holy Spirit and the understanding of spiritual truths.
