How did Paul address the carnal church at Corinth?

Les explains that even the carnal church at Corinth was addressed as the saints, those sanctified in Christ Jesus, even the Corinthians. Paul told them that by this Gospel they are saved, if they keep in memory what he preached unto them—not what Peter and the twelve in Jerusalem had, but what he preached unto them. In I Corinthians 15, verse 3, he says he preached what he also received: that Christ died for our sins, was buried, and rose again the third day according to the Scriptures. Les notes this was not a surprise; long before the universe was created, God had the whole scheme laid out and the human experience pre-planned.
