This new book presents a structured theological debate comparing Islamic and Christian perspectives on the nature of God and the human condition. It explores foundational disagreements over whether the Creator is defined by sovereign will or eternal being, and whether He can be personally known through intimacy or only rightly acknowledged through submission. The text examines key topics such as the nature of sin, the necessity of atonement, and the ultimate purpose of humanity, framed either as servitude or union. Each section follows a formal disputation format, offering arguments, rebuttals, and joint conclusions for both traditions. Ultimately, the source provides a critical adjudication that evaluates which faith offers a more coherent resolution to the problem of human alienation. Through this comparative inquiry, the work highlights the profound differences between divine transcendence in Islam and the relational nearness central to Christianity.
