Did the Corinthian church write Paul a letter asking him questions?
Yes. The Corinthian believers evidently sent the apostle Paul a letter containing a long list of questions about how they were handling the various problems in their church. That correspondence is addressed in the first letter to the Corinthians, where Paul worked through those questions as he wrote.
Les explains that the Corinthian assembly evidently sent the apostle a letter with a long list of questions as to how they were handling all these various problems, and he dealt with that as he came up through that first letter. Among the problems was gross immorality in chapter 5, which grieved the apostle that a believer would stoop to such a low level while the church was not addressing it. That was dealt with in the first letter. Les notes the second letter was probably written months, less than a year, after the first, and that Paul now gives the idea that many of these things were corrected, showing the first letter did not fall on deaf ears.
