In the Harvest Field or Praying for the Harvest?

While Dennis is in Latvia with Frank and Mitch, our wives and Christian friends are in prayer for God's work. Though we are blessed to be here, it is probably a greater blessing to be praying and lifting up those who have gone out. It says in Acts 13: "And when they had fasted and prayed, and laid [their] hands on them, they sent [them] away. So they, being sent forth by the Holy Ghost, departed unto Seleucia; and from thence they sailed to Cyprus. And when they were at Salamis, they preached the word of God in the synagogues of the Jews: and they had also John to [their] minister.
Here we see that praying and preaching were both essential.
