This certainty arises from a few very plain general considerations. The first is, that the whole system of means appointed by the Almighty to be employed as a human process for presenting religion solemnly in view before men's minds, and enforcing it on them, is an appointment _expressly intended_ for working that great effect which secures their final felicity; though to what extent in point of number is altogether unknown to the subordinate agents. They are perfectly certain, in employing the appointed expedients in prosecution of the work, that they must be proceeding on the strength of a positive relation subsisting between those means and the results to be realized, in what instances, in what measure, at what time, it shall please the sovereign Power. The appointment cannot be one of mere exercise for the faculties and submissive obedience of those who are summoned to be active in its execution. Accordingly, there are in the divine revelation very many explicit and animating assurances, that their exertions shall certainly be in a measure effectual to the proposed end. And if these assurances are made in favor of the exertions for inculcating religion generally, that is, on men of all conditions and ages, they may be assumed as giving special encouragement to those for impressing it on young minds, before they can be preoccupied and hardened by the depravities of the world. There is plainly the more hope for the efficacy of those exertions the less there is to frustrate them. But besides, the authority itself, which has assured a measure of success to religious instruction as administered generally, has marked with peculiar strength the promise of its success as applied to the young; thus affording rays of hope which have in ten thousand instances animated the diligence of pious parents, and the other benevolent instructors of children.
