"unto all good works, meant that nothing more should be written by inspiration, why was he at that moment adding to those Scriptures? At least why did he not drop the pen as soon as that sentence was written? And why did John, thirty years afterward, write the book of Revelation? This book contains another text which is quoted to prove the abolition of spiritual gifts. EW 136.3"
"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:"
EGW directly references Revelation 22:18 in her argument against the cessation of spiritual gifts, interpreting it as applying specifically to the book of Revelation itself, not the entire biblical canon. This is a clear thematic parallel.
