What does the Bible say about winning and losing in the Christian life?

In Philippians 3:7-8, Paul expresses that the things he once considered gains—his religious heritage, adherence to the law, and zeal for God—have become losses in light of knowing Christ. This paradox is rooted in the understanding that one's righteousness does not stem from personal achievements or religious practices, but solely from faith in Christ. Paul emphasizes that having a relationship with Christ surpasses all earthly gains, leading him to count everything as loss for the sake of knowing Him. This theme is echoed in Matthew 10:39, where Jesus indicates that one must lose their life to find true life in Him.
