Summary: The telling of the message: the imparting of a divine mystery.
THE APOSTOLIC TESTIMONY
Peter had a genuine pastoral concern for the purity of the church after his own death, literally his “exodus” (2 Peter 1:14-15). The Apostle wrote his second letter against a background of false teaching which denied the second coming of our Lord Jesus Christ (2 Peter 3:3-4). Therefore he called to the witness stand the apostles (2 Peter 1:16-18) and prophets (2 Peter 1:19-21), upon whose testimony the church is built (Ephesians 2:20).
Peter emphasised the genuineness of the apostolic teaching. The “telling” (2 Peter 1:16) of the message was the imparting of a divine mystery. The Apostles were not following cleverly imagined fables in need of the de-mythologising pruning knife of the new teachers.
When the Apostles spoke of the power and coming of Jesus it was no lie, but followed on from their experience of His glory in the holy mount of transfiguration. Jesus’ preaching in Nazareth (Luke 4:16-21) had already severed “the acceptable year of the LORD” from “the day of vengeance of our God” (Isaiah 61:2). As Peter unfolded his argument it would become apparent that Jesus’ first coming was in order to usher in a dispensation of mercy, but that he would just as surely have a second coming to judgement (2 Peter 3:9-10).
In the mountain Peter, James and John “beheld His glory, the glory as of the only begotten of the Father” (John 1:14). Jesus changed in His physical appearance, shining with the brightness of His heavenly glory. The witnesses saw (and heard) Moses and Elijah talking with our Lord about His death, literally “the exodus which He would accomplish at Jerusalem” (Luke 9:31).
The incarnation of Jesus was His clothing in humility, as a sacrifice for sin. The impending “coming” of the Lord Jesus speaks of His splendid arrival as judge and king. For a brief moment, in the transfiguration, the three disciples saw the veil between heaven and earth lifted, and were “eyewitnesses” of His “majesty” (2 Peter 1:16).
The silversmiths of Ephesus may give expression to the imagined magnificence of Diana (Acts 19:27), but this does not hold a candle to the divine majesty of the Person of our Lord Jesus Christ. His is the excellence of God (Deuteronomy 33:26), the honour and majesty of the Messianic king (Psalm 21:5), the glorious splendour of the majesty of the One who rules over the words and works of Providence (Psalm 145:5). This majesty was not only manifested to the three witnesses in the mount of transfiguration, but also afterwards in the valley where the people marvelled at the majesty of God (Luke 9:43) when Jesus healed a boy who was troubled by a demon.
The Apostles were being accused of misrepresentation, so having borne testimony to what they had seen, Peter now turned to his account of what they heard. Peter speaks of a commissioning from God the Father, in which Jesus received honour and glory (2 Peter 1:17). A voice was heard from “the very excellent glory,” the pillar of cloud no less, the glory which filled the tabernacle and Temple and which was now seen momentarily on the holy mount.
