Paul provides final instructions to the church in Corinth, urging them to stand firm in their faith, act with courage and strength, and do all things in love. He emphasizes the importance of recognizing and submitting to faithful, godly leaders who are devoted to ministry, help with work, and refresh the spirits of the saints. Paul concludes by reminding the Corinthians to greet one another affectionately, love the Lord Jesus Christ, know that he is coming again, and remain steadfast in God's grace. The document suggests applying these final words to the modern church in order to avoid similar problems.
