Audio Book - An Enquiry into the Obligations of Christians to Use Means for the Conversion of the Heathens written by William Carey, read by David Cochran Heath and published by Christian Audio.
In 1792, William Carey had noticed that his contemporaries no longer sought to share the Gospel with the same zeal as the new believers of the early Church. In An Enquiry, he counters this apathy with a theological justification for missions, a history of missionary activity and a survey of the world. He then turns to pesuasion, arguing against common objections to sending missionaries and convincing his readers that a missionary society should be formed. Carey's work was a success and resulted in the founding of the Baptist Missionary Society.
