How do we know that true faith leads to good works?

The relationship between faith and works is a profound aspect of Reformed theology. It is articulated in James 2:17, where it states, 'Faith by itself, if it does not have works, is dead.' This verse underscores the necessity of good works as evidence of genuine faith. A true believer, one who has been transformed by grace, will exhibit obedience as a natural outflow of their faith in Christ. The demonstration of love towards God is seen through one's actions, as Jesus highlighted the importance of doing the will of His Father (Matthew 7:21).

Additionally, historic Reformed thought affirms that while good works do not contribute to one’s salvation, they are the fruit of a true and living faith. The Spirit of God works within believers, compelling them toward acts of love and service, thus validating their faith. This interplay of faith and works is integral to understanding sanctification in the believer's life, where one grows in grace and is increasingly conformed to the image of Christ.
