Luke 10:2, “Then He said to them, the harvest truly is great, but the laborers are few. Therefore pray to the Lord of the harvest that He may send forth laborers into His harvest”.
Jesus asked us to pray that the Lord of the harvest would send forth laborers into His harvest. As I see it, Jesus did not ask us to pray that the Lord of the Harvest would call workers or give them a vision for the lost. I think that we can say that God, through the Holy Spirit, is doing great at his part of calling and giving a vision to go save the lost and train the found. However, our part, send forth laborers, is where we currently have a problem. It seems to me that part of the reason is that the responsibility of sending is given to the Church, and depends on the human involvement of people of faith.
Perhaps that is why Jesus made this prayer request! We need a renewed vision for sending. God is doing his part in the first step, the calling of workers, and in the last step of saving the lost and making disciples through the witness and labor of the workers. However, today we have a problem in that middle step of sending. God honors a step of faith and provides for those who send, but we still have to commit to it. The enemy knows that if the called are not sent, there will not be a harvest. God knew that in these last days it would be easy to be distracted and not send workers, and so that is where Jesus asked us to concentrate our prayer. We pray that God would motivate and enable our people and Churches to send.
