David Clayton teaches a class on 2 Corinthians 1:12-2:04. The class focuses on what Paul boasts about, including having a clear conscience, relying on God's works, writing plainly, wanting to be fully understood, handling accusations against him, having a consistent strategy, preaching a consistent message in Christ, and exercising careful judgment. The lesson encourages applying these lessons by reflecting on how others see you, being plainly spoken with love, being careful not to appear fickle in plans, believing in God's promises, and having courage when facing criticism from multiple sides.
