Why is it important for Christians to avoid extremes in their faith?

The Apostle Paul warns against the dangers of extremes, such as legalism and licentiousness, in Philippians 3:18-19. He illustrates that true followers of Christ are called to a narrow way that does not fall into either excess. Legalism places confidence in human efforts to earn salvation, while antinomianism suggests that freedom from the law means living without accountability. Both positions misrepresent the gospel's intent. Instead, Christians are to live in the liberty of grace while bearing fruit, demonstrating a balance that is evident in a life dedicated to pursuing holiness and serving others.
