Both the Apostles' witness and the prophetic word in the Scriptures are the shining of the truth.

在本书信里，彼得给信徒有力的见证，作为对抗异端的豫防剂。因这缘故，他指出使徒对他们说到主耶稣的来临时，并不是随从乖巧捏造的虚构无稽之事。彼得的意思似乎是说，“不要听从异端者。我同约翰和雅各在圣山上，是主威荣的亲眼见证人。祂变化形像时，我们与祂在一起，并且我们听见有声音宣告：“这是我的爱子，我所喜悦的。”我们所告诉你们的不是传说、虚构无稽之事、或迷信的故事。我们见证我们所听见、所看见的。我们看见主耶稣变化形像，并且我们知道，正如祂在变化形像时得荣耀，祂也要在荣耀里再来。你们需要接受我们的话，并且相信这话。”

在一章十九至二十一节，彼得接着用见于旧约申言者的话，证实他们的见证。使徒的见证和经上申言者的话，都是真理的照亮。这照亮是神圣供备的一部分，就是神藉着祂的能力所作的供备，使祂的选民能远离异端和背道。

In this Epistle Peter is giving the believers a strong testimony as an inoculation against heresy. This is the reason he points out that the Apostles did not follow cleverly devised myths when they spoke to them about the coming of the Lord Jesus. Peter seems to be saying, "Don't listen to the heretics. Along with John and James, I was an eyewitness of the Lord's majesty on the holy mountain. We were with Him when He was transfigured, and we heard the voice declaring, 'This is My beloved Son, in whom I delight.' What we have told you is not a legend, myth, or superstitious tale. We testified of what we have seen and heard. We saw the Lord Jesus transfigured, and we know that as He was glorified in His transfiguration, so He will come again in glory. You need to receive our word and believe it."

In 1:19-21 Peter goes on to use the prophetic word found in the Old Testament to confirm their testimony. Both the Apostles' witness and the prophetic word in the Scriptures are the shining of the truth. This shining is part of the divine provision, the provision God has made by His power so that His elect children may be able to stay away from heresy and apostasy.
