I FEAR that in some of our less enlightened country churches there are conservative individuals who almost believe that to preach anywhere except in the chapel would be a shocking innovation, a sure token of heretical tendencies, and a mark of zeal without knowledge. Any young brother who studies his comfort among them must not suggest anything so irregular as a sermon outside the walls of their Zion. In the olden times we are told "Wisdom crieth without, she uttereth her voice in the streets, she crieth in the chief places of concourse, in the openings of the gates"; but the wise men of orthodoxy would have wisdom gagged except beneath the roof of a licensed building. These people believe in a New Testament which says, "Go out into the highways and hedges and compel them to come in," and yet they dislike a literal obedience to the command.
