This first and still greatest missionary treatise in the English language closes with the practical suggestion of these means--fervent and united prayer, the formation of a catholic or, failing that, a Particular Baptist Society of "persons whose hearts are in the work, men of serious religion and possessing a spirit of perseverance," with an executive committee, and subscriptions from rich and poor of a tenth of their income for both village preaching and foreign missions, or, at least, an average of one penny or more per week from all members of congregations. He thus concludes:--"It is true all the reward is of mere grace, but it is nevertheless encouraging; what a treasure, what an harvest must await such characters as Paul, and Eliot, and Brainerd, and others, who have given themselves wholly to the work of the Lord. What a heaven will it be to see the many myriads of poor heathens, of Britons amongst the rest, who by their labours have been brought to the knowledge of God. Surely a crown of rejoicing like this is worth aspiring to. Surely it is worth while to lay ourselves out with all our might, in promoting the cause and kingdom of Christ." So Carey projected the first organisation which England had seen for missions to all the human race outside of Christendom; and his project, while necessarily requiring a Society to carry it out, as coming from an "independent" Church, provided that every member of every congregation should take a part to the extent of fervent and united prayer, and of an average subscription of a penny a week. He came as near to the New Testament ideal of all Christians acting in an aggressive missionary church as was possible in an age when the Established Churches of England, Scotland, and Germany scouted foreign missions, and the Free Churches were chiefly congregational in their ecclesiastical action. While asserting the other ideal of the voluntary tenth or tithe as both a Scriptural principle and Puritan practice, his common sense was satisfied to suggest an average penny a week, all over, for every Christian. At this hour, more than a century since Carey wrote, and after a remarkable missionary revival in consequence of what he wrote and did, all Christendom, Evangelical, Greek, and Latin, does not give more than five millions sterling a year to Christianise the majority of the race still outside its pale. It is not too much to say that were Carey's penny a week from every Christian a fact, and the prayer which would sooner or later accompany it, the five millions would be fifty, and Christendom would become a term nearly synonymous with humanity. The Churches, whether by themselves or by societies, have yet to pray and organise up to the level of Carey's penny a week.
