The Lord asked "Whom shall I send? And who will go for us?" And I said, "Here am I, Send me!" (Isaiah 6:8). If Christians don't preach the word of God; "How, then can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? And how can they preach unless they are sent? As it is written, "How beautiful are the feet of those who bring good news!" (Romans 10:14-15,NIV).
