Origin and Application:
For the past thirty years, Paul the apostle had travelled across Asia and Europe to spread the gospel. He likened his life as a preacher as warfare and a race. Looking back, he had fought the good fight in this spiritual warfare, and had stood firm in defending his faith.
“Fight the good fight” has become a metaphor for struggling against the odds regardless of the outcome. Whether one wins or loses, he has still fought the good fight. It has become a common expression used by politicians in the U.S., including former president George Bush who lost the presidential campaign in 1992.
