"The members of the church are responsible for the talents committed to their trust, and it is impossible for Christians to meet their responsibilities unless they occupy that elevated position that is in accordance with the sacred truths which they profess. The light that shines upon our pathway makes us responsible to let that light shine forth to others in such a manner that they will glorify God. 3T 53.3"
"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
The EGW passage explicitly references the idea of letting one's light shine, which is a direct allusion to Matthew 5:16. The passage expands on the responsibility of Christians to live in accordance with their faith and glorify God through their actions.
