God calls upon us to burst the bands of our precise, indoor service. The message of the gospel is to be borne in the cities and outside of the cities. We are to call upon all to rally around the banner of the cross. When this work is done as it should be, when we labor with divine zeal to add converts to the truth, the world will see that a power attends the message of truth. The unity of the believers bears testimony to the power of the truth that can bring into perfect harmony men of different dispositions, making their interests one. 1NL 11.8
The prayers and offerings of the believers are combined with earnest, self-sacrificing efforts, and they are indeed a spectacle to the world, to angels and to men. Men are converted anew. The hand that once grasped for recompense in higher wages has become the helping hand of God. The believers are united by one interest—the desire to make centers of truth where God shall be exalted. Christ joins them together in holy bonds of union and love, bonds which have irresistible power. 1NL 12.1
It was for this unity that Jesus prayed just before His trial, standing but a step from the cross. “That they all may be one,” He said, “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.” 1NL 12.2
