How is it many, whose faith and grace it would be uncharitable to deny, work so little, give so little, say so little, take so little pains, to promote Christ’s cause, and bring glory to Christ in the world? These questions admit of only one answer. It is a low sense of debt and obligation to Christ, which is the account of the whole matter. Where sin is not felt at all, nothing is done; and where is little felt, little is done.
