How do we know that faith is essential for Christians?

In the Christian life, faith acts as the foundation for all that believers do. Ephesians 6 elaborates on this by presenting faith as a crucial component of the believer's armor, specifically indicating that the shield of faith helps to extinguish the fiery darts of the wicked one. This means that faith is not merely an abstract concept but a practical force that defends against spiritual attacks and uncertainties. Christians draw strength and assurance from their faith in Christ, evidenced through the trials they endure and the promises they hold. Moreover, Hebrews 11 illustrates how faith enables believers to endure trials, foreseeing God's promises even when they remain unfulfilled. Thus, faith becomes indispensable for standing firm in the face of life's challenges.
