Those who speak to the people through our periodicals should preserve unity among themselves. Nothing that savors of dissension should be found in our publications. Satan is always seeking to cause dissension, for well he knows that by this means he can most effectually counteract the work of God. We should not give place to his devices. Christ's prayer for His disciples was: "That they all may be one; as Thou, Father, art in Me, and I in Thee, that they also may be one in Us: that the world may believe that Thou hast sent Me." John 17:21. All true laborers for God will work in harmony with this prayer. In their efforts to advance the work all will manifest that oneness of sentiment and practice which reveals that they are God's witnesses, that they love one another. To a world that is broken up by discord and strife, their love and unity will testify to their connection with heaven. It is the convincing evidence of the divine character of their mission.
