Why did the Corinthian church have so many problems despite being born again?

Les explains that it is almost discouraging that the little church of Corinth—born-again people brought out of paganism who had turned their backs on their idols—were still plagued with problems. He notes that they are in this book because we have the same problems today, making it tremendous lesson material for every one of us and for every local congregation. For instance, in 1 Corinthians 6:1, Paul asks, 'Dare any of you, having a matter against another, go to law before the unjust, and not before the saints?' The Corinthians had gotten into a real wrangle with fellow church members, and instead of taking it to the local church body, the pastor, or church leadership—elders or deacons—they were going to lawyers and the courts. Paul tells them not to go to the world's lawyers and courts with their problems but to keep it within the confines of the believers. Les acknowledges there comes a point when one may have to go to the world's judicial system, but the principle remains that the church should handle its own disputes. Thus, the Corinthian problems persisted because believers can fall into the same worldly patterns, and these examples serve as lessons for us.
