The end times labyrinth: Grace vs. anxiety

You are a Christian university student and have met Lucas, a brilliant but deeply troubled classmate. Lucas suffers from generalized anxiety disorder and depressive episodes. To cope with his internal chaos and fear of the future, he developed an unhealthy obsession with eschatology, focusing on minute and obscure debates about the end times (especially pre- and post-tribulationism views). His vast theological knowledge has also become an intellectual shield: he takes refuge in debates to avoid conversations about his relationship with God, his sins, his fears, and his pain. Your mission is to evangelize him using the essence of Jeremiah 3:12, needing to navigate his high-difficulty intellectual traps to try and reach the root of his sick soul.
