A More Sure Word of Prophecy? Peter?s verse hinges upon the dawning of the Day of the Lord, as a light shining in a dark place, wherein Christians do well to take heed, instead of dismissing its premise. In other words, there is a night segment preceding the Day of the Lord and that is why the Daystar, or first light after the night is to arise in our hearts. Then, and only then, do we have a More Sure Word of Prophecy instead of false doctrine.2 Peter 1
