Many people have found The People's Bible to be the most reliable Bible commentary series published. It's the laypeople's Bible--down to earth, clearly written, easy to read and understand, filled with practical and contemporary applications. Each volume includes that book's complete text from the NIV Bible. The Christ-centered commentaries following the Scripture sections contain explanations of the text, historical background, maps, illustrations, and archaeological information. The People's Bible commentaries are great for personal or group study.
Paul wrote 1 Corinthians because the congregation faced a series of problems, including the danger of splintering into factions and even lapsing into paganism. Other problems plagued the Corinthians as well. Paul's letter provided clear advice. The longest chapter, chapter 15, has become one of the most treasured, because it trumpets the victory of Christ's resurrection from the dead.
