Here is the urgency of prayer enforced by the compassions of our Lord. It is prayer born of compassion for perishing humanity. Prayer is pressed on the Church for labourers to be sent into the harvest of the Lord. The harvest will go to waste and perish without the labourers, while the labourers must be God-chosen, God-sent, and God-commissioned. But God does not send these labourers into His harvest without prayer. The failure of the labourers is owing to the failure of prayer. The scarcity of labourers in the harvest is due to the fact that the Church fails to pray for labourers according to His command. The ingathering of the harvests of earth for the granaries of heaven is dependent on the prayers of God’s people. Prayer secures the labourers sufficient in quantity and in quality for all the needs of the harvest. God’s chosen labourers, God’s endowed labourers, and God’s thrust-forth labourers, are the only ones who will truly go, filled with Christly compassion and endued with Christly power, whose going will avail, and these are secured by prayer. Christ’s people on their knees with Christ’s compassion in their hearts for dying men and for needy souls, exposed to eternal peril, is the pledge of labourers in numbers and character to meet the wants of earth and the purposes of heaven. God is sovereign of the earth and of heaven, and the choice of labourers in His harvest He delegates to no one else. Prayer honours Him as sovereign and moves Him to His wise and holy selection. We will have to put prayer to the front ere the fields of paganism will be successfully tilled for Christ. God knows His men, and He likewise knows full well His work. Prayer gets God to send forth the best men and the most fit men and the men best qualified to work in the harvest. Moving the missionary cause by forces this side of God has been its bane, its weakness and its failure. Compassion for the world of sinners, fallen in Adam, but redeemed in Christ will move the Church to pray for them and stir the Church to pray the Lord of the harvest to send forth labourers into the harvest. “Lord of the harvest hear Thy needy servants’ cry; Answer our faith’s effectual prayer, And all our wants supply. “Convert and send forth more Into Thy Church abroad; And let them speak Thy word of power, As workers with their God.” What a comfort and what hope there is to fill our breasts when we think of one in Heaven who ever liveth to intercede for us, because “His compassion fails not!” Above everything else, we have a compassionate Saviour, one “who can have compassion on the ignorant, and on them who are out of the way, for that he himself is compassed about with infirmity.” The compassion of our Lord well fits Him for being the Great High Priest of Adam’s fallen, lost and helpless race.
