What does the Bible say about the importance of living for Christ?

In Philippians 1:21, Paul states, 'For to me to live is Christ and to die is gain,' highlighting that the very purpose of life for believers is to glorify Christ through their actions and words. Living for Christ involves relying on Him as the source of strength and purpose, as all believers are called to advance His kingdom while on earth. This perspective underscores a robust understanding of a Christian's life as one of active service, reflecting the grace and mercy they have received due to their salvation through Jesus.
