Left to its own devices, evil will continue to corrupt everything around it until it is utterly crushed. Frodo’s mission to destroy the ring will ultimately bring that deliverance to Middle Earth if successful, but because that deliverance has never come before when he meets with Faramir in The Two Towers, if few are looking for that ultimate deliverance.
“‘What hope have we?’ said Faramir. ‘It is long since we had any hope. The sword of Elendil, if it returns indeed, may rekindle it, but I do not think that it will do more than put off the evil day, unless other help unlooked-for also comes, from Elves or Men. For the Enemy increases and we decrease. We are a failing people, a springless autumn.’”
The irony of course is that he is saying this to the only one who carries any sense of hope in Middle Earth. The entire world is going to either be renewed or be brought to inevitable destruction by the fate of Frodo or more specifically the ring. The hope of course lies in the fact that the mission is still in motion and there is still a chance that it will be destroyed. Until the mission fails, there is hope, but aside from that, there is no remaining hope in Middle Earth.
Faramir, the brother of the fallen Boromir, eventually did learn of their true mission, but his response is much different than that of his brother.
“For strange though it may seem, it was safe to declare this to me. It may even help the master that you love. It shall turn to his good, if it is in my power. So be comforted. But do not even name this thing again aloud. Once is enough.”
He recognizes now what has to be done. He does not desire to possess the ring, and he doesn’t even want to talk about it. He realizes that the mission is the most important thing, and he vows to provide whatever support he can. He wants to turn this meeting into a good thing which it does ultimately turn out being since he helps provide additional supplies and temporary safety to the hobbits.
Thinking about this in the perspective of our world then, we do believe that there is one great hope of humanity. That hope is one day going to put an end to all evil. Until that time, our mission is to be the hands and feet of Jesus Christ on earth. We are not called to overthrow Satan; we cannot bring an end to all evil by ourselves. However, we are to serve the world we find ourselves in.
Evil is going to be destroyed one day, and that will be a joyful day indeed. However, in the meantime, let’s make sure that we are aligning our purposes with Jesus Christ. We might not be able to destroy evil by ourselves, but we will be a force for good that will make a difference. I don’t know about you, but I am okay with doing my part.
