Seth uses the metaphor of caving to explain how people often choose darkness (symbolizing evil) over light (symbolizing truth), fearing that their wrongdoings will be exposed. He draws from John 3:16-21, emphasizing that Jesus is the light and that choosing truth is essential for living a life aligned with God. Seth encourages his audience to make wise decisions, reject worldly influences, and step into the light, trusting that God is at work even when they may not see immediate evidence. He concludes by challenging them to actively choose truth and faith in their daily lives.
