Revelation 22:7-13

And behold, I come quickly. Blessed is he that keepeth the words of the prophecy of this book. And I John am he that heard and saw these things. And when I heard and saw, I fell down to worship before the feet of the angel that showed me these things. And he saith unto me, See thou do it not: I am a fellow-servant with thee and with thy brethren the prophets, and with them that keep the words of this book: worship God. And he saith unto me, Seal not up the words of the prophecy of this book; for the time is at hand. He that is unrighteous, let him do unrighteousness still: and he that is filthy, let him be made filthy still: and he that is righteous, let him do righteousness still: and he that is holy, let him be made holy still. Behold, I come quickly; and my reward is with me, to render to each man according as his work is. I am the Alpha and the Omega, the first and the last, the beginning and the end.
