The key to the missionary problem is in the hand of God, and that key is prayer not work, that is, not work as the word is popularly understood to-day because that may mean the evasion of concentration on God. The key to the missionary problem is not the key of common sense, nor the medical key, nor the key of civilization or education or even evangelization. The key is prayer. "Pray ye therefore the Lord of the harvest." Naturally, prayer is not practical, it is absurd; we have to realize that prayer is stupid from the ordinary common-sense point of view.
The key to the missionary message is the propitiation of Christ Jesus. Take any phase of Christ’s work – the healing phase, the saving and sanctifying phase; there is nothing limitless about those. "The Lamb of God which taketh away the sin of the world! " – that is limitless. The missionary message is the limitless significance of Jesus Christ as the propitiation for our sins, and a missionary is one who is soaked in that revelation.
The basis of missionary appeals is the authority of Jesus Christ, not the needs of the heathen. We are apt to look upon Our Lord as One Who assists us in our enterprises for God. Our Lord puts Himself as the absolute sovereign supreme Lord over His disciples. He does not say the heathen will be lost if we do not go; He simply says – "Go ye therefore and teach all nations." Go on the revelation of My sovereignty; teach and preach out of a living experience of Me.
Moses saw the oppression of his people and felt certain that he was the one to deliver them, and in the righteous indignation of his own spirit he started to right their wrongs. After the first strike for God and for the right, God allowed Moses to be driven into blank discouragement, He sent him into the desert to feed sheep for forty years. At the end of that time, God appeared and told Moses to go and bring forth His people, and Moses said – "Who am I, that I should go?" In the beginning Moses realized that he was the man to deliver the people, but he had to be trained and disciplined by God first. He was right in the individual aspect, but he was not the man for the work until he had learned communion with God.
The test of a man’s religious life and character is not what he does in the exceptional moments of life, but what he does in the ordinary times, when there is nothing tremendous or exciting on. The worth of a man is revealed in his attitude to ordinary things when he is not before the footlights (cf. John 1:36). It is a painful business to get through into the stride of God, it means getting your second wind spiritually. In learning to walk with God there is always the difficulty of getting into His stride; but when we have got into it, the only characteristic that manifests itself is the life of God. The individual man is lost sight of in his personal union with God, and the stride and the power of God alone are manifested.
