False teachers had risen up in the church denying the return of Christ, prompting Peter to write his second letter to the churches. In 1:16-21 Peter addresses the fact that Christ is indeed returning, and he basis this on two things: His experience on the Mount of Transfiguration, when he saw a glimpse of the coming majesty of Christ, and on the Old Testament prophecies about Christ. Of these two testimonies, to the truth of Christ's return, Peter says that the written word of the prophets is more sure. Peter had his experience, but above all else, God had made His Word known through His prophets, and the written Word of God is right and true, because it is the Word of God.
