Christ's transfiguration is a prefigure of His coming.

[jidong xiao]

彼得说，使徒作主威荣的亲眼见证人。这威荣指显赫，在辉煌、尊贵、荣耀、甚至显赫荣耀里的伟大，（彼后一17，）正如主变化形像时，彼得和其他两位门徒所亲眼看见的。（太十七1～2，路九32。）

在彼后一章十六节彼得似乎说，“我们曾告诉你们，主耶稣要在荣耀里回来。这不是传说或虚构无稽之事。甚至祂在地上时，荣耀就从祂出来，祂就变化形像。我们同祂在山上时，看见祂的威荣。我们是亲眼见证人；我们被引进祂荣耀的景象。”

在本节里彼得将主的变化形像与祂的回来相题并论。这就是说，基督的变化形像是祂来临的豫像。在路加九章二十六至三十六节，主耶稣也指明，祂的变化形像是祂回来时之荣耀的豫像。

Peter says that the apostles became eyewitnesses of the Lord's majesty. This majesty denotes magnificence, greatness in splendor, honor, and glory, even magnificent glory (2 Pet. 1:17), as appeared to the eyes of Peter and the other two disciples in the Lord's transfiguration (Matt. 17:2; Luke 9:32).

In verse 16 Peter seems to be saying, "We have told you that the Lord Jesus will come back in glory. This is not a tale or a myth. Even when He was on earth, the glory came out of Him, and He was transfigured. We saw His majesty when we were with Him on the mountain. We were eyewitnesses; we were initiated into a vision of His glory."

In this verse Peter combines the Lord's transfiguration with His coming back. This means that Christ's transfiguration is a prefigure of His coming. In Luke 9:26- 36 the Lord Jesus also indicated that His transfiguration was a figure of His glory in His coming back.
