We Christians should know that our unchristian conduct cannot be kept in our own back yard. The evil birds of sin fly far and influence many to their everlasting loss. The sin committed in the privacy of the home will have its effect in the assembly of the saints. The minister, the deacon, the teacher who yields to temptation in secret becomes a carrier of moral disease whether he knows it or not. The church will be worse because one member sins. The polluted stream flows out and on, growing wider and darker as it affects more and more persons day after day and year after year.
