Works are the product of the Holy Spirit that indwells the believer, if someone has been transformed from a lost worldy man to one who now follows the way, then you would expect to see this evident in their thoughts and actions.
It would be like someone running late for a work meeting and they rush in late with a slightly dishevelled look and loose tie explaining sorry had a flat tyre on the way to work and when I went to change it you would not believe it but a Mack truck run right over the top of me making me really late for the meeting.
Well if a Mack truck ran over someone you would expect some outward signs a limp maybe, well at least more than a loose tie.
So if one claims to have the creator of the universe become his master you would expect some outward visible change in thought and deeds when one encounters the Almighty God.
