Why are good works necessary according to the Bible?

According to the Bible, particularly in James 2:18, good works are essential as they provide evidences of true faith. True faith is dynamic and leads to obedience, producing good works as its natural outcome. Ephesians 2:10 provides the understanding that believers are God's workmanship, created for good works, indicating that being called to Christ entails a life characterized by righteousness and good deeds. This relationship between faith and works emphasizes that while our salvation is not by works but by grace alone, the transformed life resulting from salvation necessarily results in active faith expressed through good works. Therefore, good works serve as a witness to others of God's transformative power in a believer's life.
