Missionaries, like ministers, are born of praying people. A praying church begets labourers in the harvest-field of the world. The scarcity of missionaries argues a non-praying church. It is all right to send trained men to the foreign field, but first of all they must be God-sent. The sending is the fruit of prayer. As praying men are the occasion of sending them, so in turn the workers must be praying men. And the prime mission of these praying missionaries is to convert prayerless heathen men into praying men. Prayer is the proof of their calling, their Divine credentials, and their work. He who is not a praying man at home needs the one fitness to become a mission worker abroad. He who has not the spirit which moves him toward sinners at home, will hardly have a spirit of compassion for sinners abroad. Missionaries are not made of men who are failures at home. He who will be a man of prayer abroad must, before anything else, be a man of prayer in his home church. If he be not engaged in turning sinners away from their prayerless ways at home, he will hardly succeed in turning away the heathen from their prayerless ways. In other words, it takes the same spiritual qualifications for being a home worker as it does for being a foreign worker. God in His own way, in answer to the prayers of His Church, calls men into His harvest-fields. Sad will be the day when Missionary Boards and Churches overlook that fundamental fact, and send out their own chosen men independent of God. Is the harvest great? Are the labourers few? Then “pray ye the Lord of the harvest to send forth labourers into his harvest.” Oh, that a great wave of prayer would sweep over the Church asking God to send out a great army of labourers into the needy harvest fields of the earth! No danger of the Lord of the harvest sending out too many labourers and crowding the fields. He who calls will most certainly provide the means for supporting those whom He calls and sends forth. The one great need in the modern missionary movement is intercessors. They were scarce in the days of Isaiah. This was his complaint: “And he saw that there was no man, and wondered that there was no intercessor.” So today there is great need of intercessors, first, for the needy harvest-fields of earth, born of a Christly compassion for the thousands without the Gospel; and then intercessors for labourers to be sent forth by God into the needy fields of earth.
