Imagine experiencing the most remarkable, amazing thing that you’ve ever seen and not telling anyone about it. That’s what happened to Peter, James, and John one day when they accompanied Jesus up a mountain to pray. While they were there, Jesus took on a radiant appearance, two of the greatest figures in Jewish history appeared, and they heard the voice of God. Imagine the significance of that experience for these men; they must have been absolutely stunned and amazed. And then imagine not saying anything about it for several months.
Remember that the author of this account, Luke, is trying to tell us something about Jesus. He’s answering the question, “Who is this?” In the previous section, Peter asserts that Jesus is “the Christ of God” (9:20). The transfiguration verifies that assertion. This event reveals the glorious, divine nature of Christ. God Himself verifies that Jesus is his beloved Son. This experience must have left no doubt in the minds of Peter, James, and John that Jesus was whom he claimed to be. I wish they would have had smart phones or cameras to record the event. They didn’t record it digitally, but they did record it verbally and then scripturally. We have the record of it here before us.
As we read this account almost 2000 years after it was written, we must conclude that Jesus is whom he claimed to be—the divine Son of God. If you believe that truth and trust in Jesus as Lord and Savior, you will be saved. If you fail to believe that truth, you cannot be saved. So it’s a very important claim to consider.
