But I do protest against the careless spirit of slumber which seems to seal the eyes of many in the church, and to blind them to the enormous perils in which we are placed by the rise and progress of false doctrine these days.
I ask you to pay special attention to this point. Such is the simplicity and innocence of many in the church today, that they actually expect false doctrine to look false, and will not understand that, as a rule, the very essence of its ability to do harm is its resemblance to God’s truth.
