Do miracles exist?

A most common question is "Do miracles exist?".
Mostly this is in reference to speaking in tongues and spiritual healing.
Harold has a ready response "Revelations 22: 18-19"
"18 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:
19 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."

Pretty simple, there are two verses after this entry into the bible, here they are:
"20 He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus.
21 The grace of our Lord Jesus Christ be with you all. Amen"

Thats the end of the word of god.
His statment means after he pronounced the word "Amen" in Revelations 22 verse 21 there were no more forms of communications, demonstrations or anything else that can be faithfully declaired as "From God".

So if you think you had a chat with god it was either your immagination, a prank or satan.
