How is 2 Corinthians different from 1 Corinthians?

In 1 Corinthians, Paul addressed a church full of problems and had to correct them; 2 Corinthians, written within a year, reflects a different attitude—encouragement, exhortation, and boasting about them to churches in Achaia and Macedonia. It also turns to grace-age giving in chapters 8 and 9.

Les explains that in 1 Corinthians Paul had to deal with a church full of problems and address them, almost feeling bad about it. Within a year, he writes 2 Corinthians with a whole different attitude: he is no longer condemning them but encouraging, exhorting, and boasting about them to other churches throughout Achaia and Macedonia, the two areas of Greece. Then he comes to a still-touchy subject, their billfold, and chapters 8 and 9 give instructions on Christian grace-age giving.

When did Paul write 2 Corinthians compared to 1 Corinthians?

Paul wrote 2 Corinthians within a year after 1 Corinthians. The exact amount of time is unknown, but it was sometime less than a year later. In 1 Corinthians he dealt with a church full of problems; in 2 Corinthians he encourages and exhorts them. This second letter reflects a changed attitude from condemnation to encouragement.
