In the 1916 Melchizedek Priesthood manual supplementing James E. Talmage’s Jesus the Christ (1915), we have the following explanation of miracles:
Miracle of transmuting water
into wine.—Miracles in general.
Give your idea of the purpose of
miracles; show that miracles are wrought in accordance with natural laws,
though perhaps not understood by man. (Melchizedek Priesthood Manual: Study for the Melchizedek Priesthood and Priests [Salt Lake City: The Church of
Jesus Christ of Latter-day Saints, 1916], 16)
