What does 1 Corinthians 16:24 mean?

Paul ends his great letter to the Christians at the church in Corinth with a simple expression of his own affection for them. He has offered harsh rebukes and demands for change in attitudes and behaviors. He is aware that some in the church already oppose him and that others may not receive this letter well. Still, Paul wants them to know everything he has written to them has been motivated by his love for them in Christ. He cares deeply for them and longs to see them thrive in their relationships with God and with each other.

How appropriate that he ends by expressing the love he has written so eloquently about (1 Corinthians 13), the love that is the greatest of all things.
