When we turn from the restless entreaties and exhortations which fill the pages of our modern missionary magazines to the pages of the New Testament, we are astonished at the change in the atmosphere. Paul does not repeatedly exhort his churches to raise money for the propagation of the Faith, he is far more concerned to explain to them what the Faith is and how they ought to practice it and to keep it. The same is true of Peter and John, and of all the apostles. They do not seem to feel any necessity to repeat the great Commission, or to urge that it is the duty of their converts to make disciples of all the nations. What we read in the New Testament is no anxious appeal to Christians to spread the Gospel, but a note here and there which suggests how the Gospel was being spread abroad: "the Churches were established in the Faith, and increased in number daily" (Acts 14:22; 16:5), "in every place your faith to Godward is spread abroad so that we need not to speak anything" (1 Thessalonians 1:8); or as a result of a persecution: "They that were scattered abroad went everywhere preaching the Word" (Acts 8:4).” This is the Spirit’s natural work!
