How does worldview form in the first place?
Every human seeks answers to four basic questions:
1) Who am I?
2) Where am I?
3) Why is the world broken?
4) How can it be fixed?
Now, here's the surprising part: Every human, every culture, every race answers these four questions with a foundational story.
Think about it. Try to answer those questions for yourself without eventually getting back to some sort of narrative that explains origins. It’s impossible. All of our values, beliefs, theologies, rituals, songs, prayers, sermons, and creeds are rooted in story, whether explicitly or implicitly.
It is from our story that our worldview blooms.
Let's pull back and look at the big picture:
The 4 existential questions are answered with story from which worldview blooms, which produces values & beliefs that are manifested by behaviors.
So, back to our original question: How do we engage someone at the deep level of worldview?
Answer: We aim for their story.
In order to produce cracks in a worldview, their story must be called into question. And, the only way their story will be called into question is by the hearing of a better story. We have to tell a better story.
What constitutes a better story? A better story more adequately answers the four fundamental questions.
God's Sacred Story, the gospel, answers the four basic questions like no other story on earth.
