The Dance of Works and Faith - Galatians, Part 5

In my experience one of the most underappreciated aspects of Christianity is the nuance of works and faith. While the scripture makes it clear that we cannot earn our salvation through self-improvement or good works. However, our relationship with the Holy Spirit is to so affect our lives that we are, indeed, characterized by good works. How do works and faith work together?

Galatians 3:2
I would like to learn just one thing from you: Did you receive the Spirit by observing the law, or by believing what you heard?
