Note 4 at 2 Cor. 1:14: In verse 13, Paul is stating that his letters had been obvious and plain, as sincere and godly as his conduct. His letters had been plain to read and easy to understand.

In verse 14, Paul reminds them that in the past he had been the cause and object of their rejoicing, at least in part. They were certainly the cause and object of Paul's rejoicing for all the good things the Lord accomplished at Corinth. He would continue to rejoice in them until the day that Jesus Christ returns.

These verses add a personal touch to Paul's letter and solicit an emotional response from those who owed their very lives to Paul. Certainly, many of the Corinthians responded favorably to this.
