And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be.
God's character seals this book: He is faithful and true, and He would never send His holy angels to deceive His saints with mere dreams. That the angel refused John's worship, reproved him for it, and the apostle confesses his own relapse into folly shows a sincerity no deceiver would display. The book stands open for all to study, compare, and test against what comes to pass.
