An Enquiry into the Obligations of Christians to Use Means for the Conversion of the Heathens In Which the Religious State of the Different Nations of the World, the Success of Former Undertakings, and the Practicability of Further Undertakings, Are Considered

In this thoughtful enquiry, the author asks a simple yet profound question: what responsibility do believers have to bring the Gospel to those who have never heard it? By surveying the religious condition of nations across continents, he paints a vivid picture of both ancient and modern faith landscapes. The opening chapters weave scriptural reflections with historical examples, showing how earlier missionary efforts have shaped the world.

From the fall of Adam to the rise of scientific rationalism, he argues that sin has worn countless disguises, yet the call to proclaim Christ remains unchanged. The work evaluates previous successes—such as the spread of Christianity among Greeks, Romans, and distant tribes—while candidly acknowledging the vast populations still untouched by the message. Concluding with a practical appeal, the author urges modern Christians to consider their part in a collective mission, balancing charitable generosity with earnest evangelistic effort.
