Behold, I stand at the door, and knock: if any man hears my voice, and opens the door, I will come in to him, and will eat with him, and he with me.

I know your works: behold, I have set before you an open door, and no man can shut it: for you have a little strength, and have kept my word, and have not denied my name.

After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up here, and I will show you things which must be hereafter.
