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

I know thy works (behold, I have set before thee a door opened, which none can shut), that thou hast a little power, and didst keep my word, and didst not deny my name.

After these things I saw, and behold, a door opened in heaven, and the first voice that I heard, a voice as of a trumpet speaking with me, one saying, Come up hither, and I will show thee the things which must come to pass hereafter.
