In 2 Peter 1:19-21, the apostle Peter presents a sure word that believers can depend upon completely. As Peter approaches the end of his earthly ministry, he directs his readers not to apostolic successors or church tradition, but to the prophetic Word of God. This passage reveals that Scripture's testimony is absolutely dependable—more certain than even eyewitness accounts. Peter describes God's Word as a lamp shining in a dark place, illuminating dangers and guiding believers until the day dawns and the morning star rises. The prophetic word encompasses the entire Old Testament and New Testament revelation, all anticipating Christ's return in glory. Unlike cleverly devised myths, Scripture provides a sure word that is fixed in meaning, divine in origin, and utterly reliable. Believers do well to pay attention to this lamp, clinging to its light in a murky world filled with errors and false teaching, until Christ returns to usher in the messianic age.
