Revelation 22:20

He which testifieth. That is, Christ. The specific reference is to the testimony in vs. 18, 19.

Surely. Gr. nai, a term of strong affirmation, like the Old English “verily.”

Quickly. The Master reaffirms the surety and imminence of His second coming (see chs. 3:11; 22:7, 12; see on ch. 1:1).

Amen. Compare chs. 1:6, 7, 18; 3:14; 5:14; 7:12; 19:4. For the meaning of the term see on Matt. 5:18. This Amen is probably spoken by the apostle. If so it should be connected with what follows thus: “Amen, come, therefore Lord Jesus.”

Come, Lord Jesus. Textual evidence may be cited (cf. p. 10) for the reading, “come, Lord Jesus Christ.” This exclamation is John’s response to the testimony of Jesus, who assures the apostle that He is coming quickly (cf. on ch. 1:1). John was probably reminded of that night in the upper room, more than half a century before, when he heard Jesus declare, “I will come again” (John 14:3), and of that day a few weeks later, on the Mount of Olives, when he had heard the angels say, “this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven” (Acts 1:11). Now, while in holy vision, John is given one last assurance that his blessed Lord is to return, and that, quickly. This assurance comes from the lips of his Master Himself, the faithful and true witness. His heart thrills at the words, and with eager anticipation he looks forward to the day when in reality, not in vision, he will see his blessed Lord face to face.
