In the book of Isaiah, the Lord asked the prophet a very profound question. "And I heard the voice of the Lord saying, 'Whom shall I send, and who will go for us?'” It was this question Isaiah faced as he uttered his passionate reply, a reply that echoes in our own hearts. This is why we go, and this is why we will continue to go as long as the Lord enables us to go. "Then I said, 'Here I am! Send me.'”
