Jesus said that He was sending out His laborers "as lambs in the midst of wolves." [Luke 10:3] The Good Shepherd is the one sending and He is the one who will guard and protect. He is always near and will be present even during danger.
In Luke 10:2 Jesus told the seventy, "The harvest is plentiful, but the laboreres are few; therefore, pray earnestly that the Lord of the harvest will send out laborers into His harvest." If the laborers Jesus is speaking to are the pray-ers, then perhaps He intended the pray-ers to become the laborers. Hmmm. Go and pray; pray and go.
Luke 10 begins "Now after this the Lord appointed seventy others, and sent them two and two ahead of Him to every city and place where He Himself was going to come." Their message? The Kingdom of Heaven is near. The Kingdom is still near; it is come and it has yet to come. "And He said to them 'The harvest is plentiful, but the laboreres are few; therefore, beseech the Lord of the harvest to send out laborers into His harvest.' "
