What does 1 Corinthians 15:31 mean?

The mission to take the gospel to those who have never heard sometimes results in a dangerous and costly life. The apostles were especially persecuted and troubled. Paul knew this better than most (2 Corinthians 11:24–28). He has been constantly under threat from Jewish religious leaders and Roman government officials, in addition to continuing the often under-funded work of a traveling evangelist and missionary.

Paul tells the Corinthians in this verse that he boasts about their coming to Christ as one of the success stories of his ministry. All of that would be worthless, he implies, if there was no resurrection from the dead. There would be no point to his dying "every day," likely meaning that he faced the real possibility of death constantly for the sake of Christ.

The point Paul makes here is one of his own sincerity. Would he continue to do any of this if Christ had not been resurrected and if none of those who follow Christ would be, either?
