First Corinthians, or First Corinthians, was written by the Apostle Paul (who wrote about half of the New Testament).
It is a letter, or epistle, to the church in the city of Corinth (the first of two that Paul wrote; see Second Corinthians for the second letter). It was written about the same time as Romans.
The book of first Corinthians is a practical letter of instruction revolving around life issues and addressing problems.
As such, it is not a cohesive book with a unifying theme, but instead a series of teachings that were appropriate to the issues and struggles that faced the Christian church in Corinth.
A reoccurring theme in First Corinthians is the tension between the church and the world, that is godly living versus a worldly lifestyle. As such it’s a most appropriate and applicable book for our present age.
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 1,000-page website ABibleADay.com to encourage people to explore the Bible. His main blog and many books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
