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 laborers to be sent into the harvest of the Lord. The harvest will go to waste and perish without the laborers, while the laborers must be God-chosen, God-sent, and God-commissioned.

But God does not send these laborers into his harvest without prayer. The failure of the laborers is owing to the failure of prayer. The scarcity of laborers in the harvest is due to the fact that the church fails to pray for laborers 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.
