Deus Irae by Philip K. Dick

In a post-apocalyptic world ravaged by nuclear war, humanity grapples with the consequences of its own destructive nature. The story follows Tibor McMasters, a limbless artist on a quest to find and paint the image of the elusive god-like figure responsible for the devastation, known as the "God of Wrath." As Tibor embarks on his journey through a landscape filled with mutated creatures and religious zealots, he encounters various philosophical and moral dilemmas, ultimately questioning the nature of divinity, faith, and the human condition in a world teetering on the brink of despair.
