Soul-winning is the chief business of the Christian minister; indeed, it should be the main pursuit of every true believer. . . . We do not regard it to be soul-winning to steal members out of churches already established, and train them to utter our peculiar Shibboleth: we rather aim at bring souls to Christ than at making converts to our synagogue. . . . Our grand object is not the revision of opinions, but the regeneration of natures. We would bring men to Christ, and not to our own peculiar views of Christianity. Our first care must be that the sheep should be gathered to the Great Shepherd; there will be time enough afterwards to secure them for our various folds. To make proselytes, is a suitable labour for Pharisees: to beget men unto God, is the honourable aim of ministers of Christ.
