Synthesized answer
The provided passages do not contain enough information to answer the question of what questions remain unanswered. The description of "Flywheel" focuses on the protagonist, Jay Austin, and his realization that his pursuit of success had led him to trade his integrity, his relationship with his wife, and his time with his son for things of no eternal significance [Page 4 of cover]. It details his spiritual awakening as God "slowly unraveled everything" to reveal the emptiness of his life [Page 4 of cover].
However, the passages do not mention any specific unanswered questions that arise from Jay Austin's story or his newfound understanding. Therefore, I cannot determine what questions remain unanswered based on the given text.

From the book
Title: Flywheel by Eric Wilson Description: "Jay Austin did what it took to get ahead and make the quick sell at work. Problem was-- the more successful he was, the more he traded what really mattered. His integrity. His relationship with his wife. His time with his son. He was chasing things that had no eternal significance. It wasn't until God slowly unraveled everything that he saw how empty his life had become."--Page 4 of cover.
