I once heard a sermon preached on Revelations 21:1 "And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea." The Pastor lamented the fact that there would not be a sea, as he was very fond of the ocean. He went on to explain that while John was writing the book of revelations he was in prison on an island, and the sea represented isolation. In heaven, isolation will no longer exist.
I can't help but imagine that a large percentage of the people we serve in Peru, feel the same sense of isolation due to the dense jungle. One day there will be a new heaven and new earth where these types of geographical challenges no longer exist, until then we will keep using the airplane to break through the isolation with the love of God.
