A.B. Simpson emphasizes the supernatural hope of Christ's return, urging believers to look forward to the glorious appearing of Jesus as a remedy against the skepticism of modern thought. He critiques the evolutionary mindset that dismisses divine intervention in history, asserting that both nature and scripture testify to a future transformation and resurrection. Simpson illustrates this hope through biblical figures like Enoch, Noah, and Abraham, who exemplified faith in God's promises. He concludes that this hope not only inspires Christian living and service but also serves as a powerful message to the world, calling for repentance and readiness for the coming King.
