...how will anyone Go ...without being Sent?

Romans 10: 14-15 - But how can they call on him to save them unless they believe in him? And how can they believe in him if they have never heard about him? and how can they hear about him unless someone tells them? And how will anyone go and tell them without being sent? This is what the Scriptures mean when they say, “How beautiful are the feet of those who bring good news!”
