How do we know good works are important for Christians?

The New Testament consistently emphasizes the importance of good works as a reflection of a believer's faith. In Matthew 5:13-16, Jesus instructs His disciples to be the salt and light of the world, implying that their actions should manifest a faith that stands out. Furthermore, John 14:15 reminds believers that love for Christ is demonstrated through obedience to His commands. The expectation is that through good works, Christians serve not only God but also bear witness to others, showcasing the transformative power of the Gospel in our lives.
