Days of Heaven Upon Earth is a year-long devotional that arranges brief daily meditations around Scripture texts, moving through themes of consecration, healing, guidance, suffering, victory, and mission. Simpson writes in aphoristic, hymn-kissed prose, stitched with biblical allusion and pastoral exhortation. Situated within the late-nineteenth-century deeper life stream associated with Keswick and Niagara, the book invites readers to anticipate eschatological fullness as present foretaste. A. B. Simpson (1843-1919), pastor-evangelist and founder of the Christian and Missionary Alliance, penned these meditations out of urban ministry in New York and a lifelong quest for the Fourfold Gospel-Christ as Savior, Sanctifier, Healer, and Coming King. His experience of physical weakness, missionary urgency, and holiness conventions shaped his conviction that daily, Spirit-enabled trust could transfigure ordinary toil into abiding communion. Readers seeking historically rooted spiritual formation will find in these pages a disciplined companion: concise enough for busy days, substantive enough to steady vocation and prayer. Students of American evangelicalism will recognize its kinship with Andrew Murray and F. B. Meyer, yet its missionary horizon is distinctly Simpson's. Receive it as a liturgy of expectancy, training the heart to live tomorrow's heaven in today's work.
