What does 1 Corinthians 16:13 mean?

In wrapping up this letter, Paul has been addressing the details of some business matters, as well as the travel plans of himself and others. He turns to sending greetings in a moment, but first he inserts a series of five quick commands. Paul's habit of doing this at the end of letters reminds one of a parent restating quickly all the things their child needs to remember before rushing out the door.

Paul tells them to be watchful or to stay on their guard, along with the command to stand firm in the faith. He may be emphasizing his teaching in the previous chapter about their faith in the resurrection of Jesus from the dead and the resurrection of all who follow Him. Some had watered down their belief in the resurrection. Paul reminded them the resurrection was essential to the gospel in which they stood (1 Corinthians 15:1). He urged them to be steadfast and immovable (1 Corinthians 15:58). They must be on the lookout for any kind of false teaching.

Paul also tells them to act like men, or to "be men of courage," and to be strong. He has made clear that their faith in Christ will face opposition from the culture around them. They must be resolved to remain in their faith with strength and courage.

Paul adds one more command in the following verse.
