This was one of those times when Jesus sternly rebuked Peter after the latter spoke against the necessity of the Passion: “Get behind me, Satan!” He said. ”You do not have in mind the things of God, but the things of men.” (vs.33b)
Six days later, Peter (along with James and John) got a preview of the coming kingdom. Jesus took these select disciples “up a high mountain where they were alone” (9:2a). There Jesus was “transfigured before them” (vs.2b). Jesus was glorified, and His clothes became dazzling white (vs.3).
Then an equally-grand event occurred: Elijah (a representative of the prophets) …and Moses (the Old Testament deliverer and law giver) -- joined Jesus. This was significant as Jesus was the One who would fulfill the work of both to these ancient kingdom workers.
From the midst of his emotional trauma Peter made a fascinating suggestion... that they erect “three shelters” -- one for Jesus…and for each of the Old Testament guests (vs.5). But before a response could be made, the last scene of this glorious event occurred: “Then a cloud appeared and enveloped them, and a voice came from the cloud: “This is My Son whom I love. Listen to Him!” (vs.7)
As quickly the transfiguration began, it came to an end. In wonderment, the three disciples now stood alone with Jesus on that high mountain. One can only begin to appreciate what they must have thought and felt.
What had happened could not be denied. They were the first followers to see Christ in all His glory -- as they would see Him after His resurrection. They had additional evidence of His true nature as the Son of God…and the promised Savior -- the very One whom Peter had earlier confessed (8:29b). This was a part of the equipping for the courageous work that lay before them as Jesus’ core disciples.
