How do we know that good works are important for Christians?

In the context of sovereign grace theology, good works are vital for Christians because they are an expression of faith that stems from divine grace. Ephesians 2:10 states that we are created in Christ Jesus for good works, which God prepared beforehand. This indicates that good works are not mere afterthoughts but central to the Christian life. Moreover, as believers, our actions serve to glorify God, validate our faith, and witness to others about the transformative power of the gospel. Thus, good works confirm that a person's faith is alive and active, not dead or dormant.
