The Prophet Isaiah, looking down the centuries with the vision of a seer, thus expresses his purpose to continue in prayer and give God no rest till Christ’s kingdom be established among men: “For Zion’s sake will I not hold my peace, and for Jerusalem’s sake I will not rest till the righteousness thereof goeth forth as brightness, and the salvation thereof as a lamp that burneth.” Then, foretelling the final success of the Christian Church, he thus speaks: “And the Gentiles shall see thy righteousness, and all kings thy glory, and thou shalt be called by a new name, which the mouth of the Lord shall name.” Then the Lord, Himself, by the mouth of this Evangelical prophet, declares as follows: “I have set watchmen upon thy walls, O Jerusalem, which shall never hold their peace, day nor night. Ye that make mention of the Lord, keep not silence. And give him no rest till he establish and till he make Jerusalem a praise in the earth.” In the margin of our Bible, it reads, “Ye that are the Lord’s remembrancers.” The idea is, that these praying ones are those who are the Lord’s remembrancers, those who remind Him of what He has promised, and who give Him no rest till God’s Church is established in the earth. And one of the leading petitions in the Lord’s Prayer deals with this same question of the establishing of God’s kingdom and the progress of the Gospel in the short, pointed petition, “Thy kingdom come,” with the added words, “Thy will be done on earth as it is done in heaven.” The missionary movement in the Apostolic Church was born in an atmosphere of fasting and prayer. The very movement looking to offering the blessings of the Christian Church to the Gentiles was on the housetop on the occasion when Peter went up there to pray, and God showed him His Divine purpose to extend the privileges of the Gospel to the Gentiles, and to break down the middle wall of partition between Jew and Gentile. But more specifically Paul and Barnabas were definitely called and set apart to the missionary field at Antioch when the Church there had fasted and prayed. It was then the Holy Spirit answered from heaven: “Separate me Barnabas and Saul for the work whereunto I have called them.” Please note this was not the call to the ministry of Paul and Barnabas, but more particularly their definite call to the foreign field. Paul had been called to the ministry years before this, even at his conversion. This was a subsequent call to a work born of special and continued prayer in the Church at Antioch. God calls men not only to the ministry but to be missionaries. Missionary work is God’s work. And it is the God-called men who are to do it. These are the kind of missionaries which have wrought well and successfully in the foreign field in the past, and the same kind will do the work in the future, or it will not be done.
