Why is it important for Christians to understand the difference between grace and works?

For Christians, grasping the difference between grace and works is vital because it shapes their understanding of God, worship, and the assurance of their salvation. If believers think they can contribute to their salvation through works, it diminishes the glory of God's grace and leads to a distorted view of worship, where a works-based mentality fosters insecurity in one's standing before God. Recognizing that salvation is entirely by grace empowers believers to trust fully in Christ's finished work and to understand that their worship is directed at the sovereign God who saves purely out of His grace, eliminating any room for boasting in human effort.
