Jesus told his disciples to pray that God would send more workers to tell his message to those who were ready to respond.

Matthew 9:35-38

35 Then we went with Jesus through many of [HYP] the cities and towns in Galilee district. He was teaching ◄in the synagogues/in the Jewish meeting places►, and preaching the good message about how God rules over people’s lives. He also was healing the people who had various diseases and illnesses. 36 When he saw the crowd of people, he pitied them because they were harassed and dejected. They were like sheep that do not have a shepherd [SIM]. 37 Then he gave this illustration to us disciples: “The people who are ready to receive my message are like a field that is ready to be harvested {for people to harvest}. But there are only a few of you who are teaching people my message. 38 So pray and ask the Lord God to send more workers who will gather people together and teach them my message, just like a landowner sends workers into his field to gather the [MET] harvest.”
