I will first suppose myself addressing one of the vast number of thoughtless creatures who have hitherto been utterly unconcerned about religion, and will try what can be done, by all plainness and earnestness of address, to awaken him from this fatal lethargy ...

In an humble dependence on which, I shall then enter on the consideration of several cases which often occur in the Christian life, in which particular addresses to the conscience may be requisite and useful.
