All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Matthew 28:18-20. UL 112.1
The lessons on the parable of the vineyard and of the two sons come close home to all who have had the light of truth.... The instruction contained in these parables is of great value. All who are bearing responsibilities, be these responsibilities great or small, should study this instruction carefully. God looks for fruit from His vineyard. This fruit is the result of the work of His laborers. Every soul who believes in Christ has a work to do for Him. No true Christian can be idle in this time of such solemn importance.... UL 112.2
Have you become a silent partner? ... There are in our world many large cities in which the truth has not yet been proclaimed. Why should not the people of these cities hear the gospel message for this time? Has not Christ purchased them with His own blood? Are they not of as much value in His sight as those who have already received the truth? Are these portions of His vineyard to be left unworked, while upon other portions blessings are poured so abundantly that they are not appreciated? The truth is not appreciated, not being mixed with faith in them that hear, because they do not arouse and give to others the light they have received.... UL 112.3
Christ's last words to His disciples show the importance to be placed on the work of spreading the truth. Just before His ascension He gave them the commission, “Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world” (Matthew 28:19, 20). UL 112.4
Christ did not confine His labors to one place. Of His work we read, ... “And he said unto them, I must preach the kingdom of God to other cities also: for therefore am I sent. And he preached in the synagogues of Galilee” (Luke 4:43, 44). UL 112.5
Would that all who have the light of truth would follow the example set by Christ, and not expend their God-given time and ability and means in one or two places, when the light of truth is to go to all the world. The wonderful display of grace shown in the gospel message is to be carried to all places.—Letter 92, April 8, 1902. “To My Brethren in Responsible Positions in the Medical Missionary Work.” UL 112.6
