"The Lord desires you to study your Bibles. He has not given any additional light to take the place of His Word." Selected Messages vol.3, p.29 E.G.W.

For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book. Revelation 22:18,19
