It is significant that all three synoptic Gospels record the narrative of the Transfiguration immediately following this prediction of Jesus. There is no break in the narrative- no chapter or verse division in the Greek original- and furthermore all three gospels mention the fact that the transfiguration occurred about a week after the statement, implying that the event was the fulfillment of the prediction.
The transfiguration was a miniature demonstration of the Second Coming. That’s how Peter understood it (2 Peter 1:16-18). So, some of the disciples were permitted to see a miniature representation of Christ’s Second Coming.
In the Transfiguration, Moses and Elijah appeared with Christ. Moses represents the dead that will be raised at the second coming (Moses received a special resurrection by our Lord- Jude 9) and Elijah represents the people that would not see death and will be alive at the Second Coming (Elijah did not see death but was taken to heaven alive – 2 kings 2:11).
