2 Peter 1:19

2 Pet. 1:19. " We have also a more sure word of prophecy, whereunto ye do well that ye take heed, as unto a light that shines in a dark place, until the day dawn, and the day-star arise in your hearts." By the word of prophecy is here meant, the standing written revelation that God had given to his church, as appears by the two next verses. This is spoken of as surer than a voice from heaven. But the apostle has a special respect to the prophetical part of this written revelation, and most of all those parts that speak of the glory of Christ's kingdom, which is the principal subject of scripture prophecy, particularly that prophecy in the 7th chapter of Daniel, that speaks of the kingdom of heaven. This word of prophecy is as a light that shines in a dark place. The time of Christ's coming is here spoken of as the morning, when Christ, who is the Sun, shall arise and appear; and his happy kingdom that he shall then set up, is represented as the day time. But the time that goes before that, is here represented as night time, or a time of darkness, and we that live in that time, as being in a dark place. The word of prophecy is as a light shining in a dark place, or as the light of a bright star in this night, a light preceding the day of Christ's coming, like the morning-star that is a forerunner of the day. The prophecies of that day foretell it, as the day-star foretells the approaching day. The prophets were harbingers of that blessed season, as the morning-star is the harbinger of the day. By the prophecies of that day that go before it, something of the light of that day is manifested beforehand, and so is reflected to it, so that some of the light of the fire is anticipated, as by the day-star while it is yet night. If we give heed to those prophecies, we shall enjoy this foregoing light in our hearts, and so this day-star will arise; then our faith in these prophecies will be the evidence of that glorious Sun that is now not seen, and will render his light that is hoped for in some measure present in this dark world, and in our dark hearts. We shall in a measure have the joy of the morning of Christ's coming beforehand; we shall have a light in our hearts that will be an earnest and forerunner of the glorious light of that day, as the dawning of the day before sun-rise.

This world is a dark place without Christ, and therefore is dark till he comes, and until his kingdom of glory is set up. It appeared to be so now, especially in the circumstances of the Christians that the apostle now writes to, a world of heresies, grand delusions, and dreadful wickedness. They were in a dark place; they were not only surrounded with heathens, and subject to persecution, as appears by Peter's first epistle, that was written to the same Christians, as is evident by 2 Peter 3:1, but were in the midst of vile heretics and apostasies, as has been said already, and Christ delayed his coming, and they had many temptations to deny the present truth, and lose their hopes of the sun's rising. When a man is in a dark place, and is in danger of stumbling and falling, and being lost, and has a light held forth to him, to guide him in, it behooves him to take heed to it, and keep his eye upon it, lest he get out of the way and fall into mischief.
