在十九节，“并”字指明除了前几节所说主变化形像的真实，用以豫防迷信的虚构无稽之事，还有先知之话的真实，作更确定的证实。彼得说到他对主在变化形像时之荣耀的个人经历以后，接着用先知的话证实并加强他的见证。
彼得把经上豫言的话比作照在暗处的灯。这指明今世乃是黑夜里的暗处（罗十三12），这世上的人都是在黑暗里行走、活动。这也指明经上先知的话犹如信徒的明灯，传输属灵的光（不仅供人心思理解的字句知识），照耀在他们的黑暗里，引导他们进入光明的白昼，甚至经过黑夜，直到主显现的那日，天发亮的时候。在主这阳光显出以前，我们需要祂话的光，照耀我们的脚步。暗处，原文也可译为阴暗地方。这是个隐喻，说明背道时的黑暗。今世是黑暗、阴暗、肮脏的地方，但先知的话是照在暗处的灯。
彼得说，我们留意先知的话，直等到天发亮，晨星在我们心里出现，我们就作得好了。这也是隐喻，说明满了亮光的时候即将来到，如同晴天破晓，有晨星于黎明前在那些蒙光照的信徒心里出现，这些信徒藉着留意经上照亮人的豫言之话，得了光照而被照明。在背道的时期，信徒留意这事，就作得好，使先知的话如同明灯，照透背道的黑暗，直等到天这样向他们发亮。这促使并鼓励他们切切寻求主的同在，并且儆醒，使他们当主在祂来临（巴路西亚）的隐密部分，像贼一样来到时，不至于见不到主（太二四27，帖后二8）。因此这隐喻必是将来世，国度时代，比作那要在主显现（来临）时（彼后一16）发亮的天；那时主是公义的日头（玛四2），祂的光要照耀出来，冲破今世黑夜的幽暗。在这之前，主要在黑夜最深时，像晨星一样（启二28，二二16），向那些儆醒渴望祂显现的人显现（提后四8）。他们因着先知之话的照耀蒙了光照，这话能把他们引到那要发亮的天。圣经如灯照在暗处的话，我们若留意，会叫我们在基督作晨星实际显出前，就得着祂在我们心里出现，照耀在我们所处之背道的黑暗中。

Be Watchful and Prepared – Take Heed to the Prophetic Word – 2 Pet. 1:19
In 2 Peter 1:19 “and” indicates that in addition to the truth of the Lord’s transfiguration covered in the preceding verses as the inoculation against superstitious myths, the truth of the prophetic word is used for a more sure confirmation. After Peter’s speaking of his personal experience of the Lord’s glory in his transfiguration, Peter goes on to use the word of the prophets to confirm his testimony and strengthen it.
Peter likens the word of prophecy in the Scripture to a lamp shining in a dark place. This indicates that this age is a dark place in the dark night (Rom. 13:12) and that all the people of this world are moving and acting in darkness. It also indicates that the prophetic word of the Scripture, as the shining lamp to the believers, conveys spiritual light to shine in their darkness (not merely knowledge in letters for mental apprehension) and guides them to enter into a bright day, even to pass through the dark night until the day of the Lord’s appearing dawns. The Greek words rendered “dark place” may also be translated murky place, a place that is squalid, dry and neglected. It is a metaphor, illustrating the darkness in the apostasy. This age is a dark, murky and squalid place, but the prophetic word is a lamp shining in the darkness.
Peter says that we do well to give heed to the prophetic word until the day dawns and the morning star arises in our hearts. This also is a metaphor, illustrating a time coming which will be full of light, as a bright day dawning, with the morning star, before dawn, rising in the hearts of the believers, who are illuminated and enlightened by giving heed to the shining word of the prophecy of Scripture. In the time of apostasy the believers do well to give heed in this matter so that the prophetic word, as a lamp, may shine through the darkness of apostasy until such a day dawns upon them. This will cause and encourage them to earnestly seek the Lord’s presence and be watchful that they not miss the Lord in the secret part of his parousia, when he comes as a thief (Matt. 24:27; 2 Thes. 2:8). Hence, this metaphor should allude to the coming age, the age of the kingdom, as a day that will dawn at the appearing (the coming) of the Lord (2 Pet. 1:16), as the Sun of righteousness (Mal. 4:2), whose light will shine to break through the gloom of the dark night of this age. Preceding this, the Lord will appear as the morning star (Rev. 2:28; 22:16) in the darkest hour of the night to those who are watchful and looking for his dear appearing (2 Tim. 4:8). They have been enlightened by the shining of the prophetic word, which is able to lead them to the dawning day.
