I was presenting a missionary discussion to a family in my mission field many years ago. The parents were polite but distant. The daughter, however—a young lady about 18 or 19—was enthralled. The idea of a living prophet aroused in her a remarkable enthusiasm, and she had many questions. I was delighted to answer them. I explained that David O. McKay was a prophet in the same way that Jeremiah and Isaiah and Moses were prophets, and that the Lord revealed his will to his children through his living prophets as he had done in ancient times.
