Life is filled with peaks and valleys. A peak is something excellent that happens in your life, something great, something to celebrate and remember. The birth of your child – that is a highpoint in your life. The day you get married – that is a peak. During those moments, it’s easy to be a Christian. “God is good,” you think to yourself. There’s no doubt in your mind that God is blessing you.

But life isn’t one peak after another. There are the valleys too. The troubles of life. Those difficult moments. When you have been diagnosed with cancer – that’s a valley. When a loved one dies – that’s a valley. During those moments, it’s more difficult to be a Christian sometimes. When you’re in the valley, it’s hard to say, “God is good.” Sometimes your faith is shaken. There’s some doubt there, when you’re in a valley, that God is blessing you and those around you.

Peaks and valleys – where are you right now? Are you on top of a peak? Or are you in a valley? Maybe you’re somewhere in between – maybe there’s a peak or a valley for you right around the corner, and you don’t even know it. The disciples of Jesus Christ had no idea that they were about to enter a valley – they were about to go through a low-point with Christ. Things with Jesus seemed to be going so well – he had performed miracles – walking on the water, feeding the 5000. He had been surrounded by crowds of people, listening to his parables. It was easy to be a disciple of Jesus at that time. There was no doubt that this was the Son of God, the Savior of the world. The disciples were experiencing one high-point after another with Jesus.

Right around the corner loomed the valley of the shadow of death. The crowds would soon turn against Jesus. He’d be betrayed, and arrested, and tortured, and publicly condemned, and executed in the most shameful way known to man at that time. The valley was right around the corner. The disciples would be filled with fear and doubt that Jesus was the Son of God. Soon, it would be very difficult to be a disciple of Christ. A deep, dark valley was right around the corner, and the disciples had no idea.

That is why today, Jesus takes them to the top of a mountain. He lets them experience something amazing – with their own eyes, they catch a glimpse of his glory. Right before the valley, Jesus takes them to a mountain, to a high point, and he does this to strengthen them for the difficult road ahead.

About a week after Jesus plainly told His disciples that He would suffer, be killed, and be raised to life (Luke 9:22), He took Peter, James and John up a mountain to pray. While praying, His appearance changed into a glorified form, and His clothing became dazzling white. Moses and Elijah appeared and talked with Jesus about His death that would soon take place. Peter, not knowing what he was saying and being very fearful, offered to put up three shelters for them. This is undoubtedly a reference to the booths that were used to celebrate the Feast of Tabernacles, when the Israelites dwelt in booths for 7 days (Lev. 23:34–42).

Peter was expressing a wish to stay in that place. When a cloud enveloped them, a voice said, “This is My Son, whom I have chosen, whom I love; listen to Him!” The cloud lifted, Moses and Elijah disappeared, and Jesus was alone with His disciples who were still afraid. Jesus warned them not to tell anyone what they had seen until after His resurrection. The three accounts of this event are found in Matthew 17:1-8, Mark 9:2-8, and Luke 9:28-36. Any event mentioned in three Gospels is significant in Jesus' life.

Undoubtedly, the purpose of the transfiguration of Christ into at least a part of His heavenly glory was so that the “inner circle” of His disciples could gain a greater understanding of Jesus. Christ underwent a dramatic change in appearance in order that the disciples could behold Him in His glory. The disciples, who had only known Him in His human body, now had a greater realization of the deity of Christ, though they could not fully comprehend it. That gave them the reassurance they needed after hearing the shocking news of His coming death.

Symbolically, the appearance of Moses and Elijah represented the Law and the Prophets. But God’s voice from heaven – “Listen to Him!” - clearly showed that the Law and the Prophets must give way to Jesus. The One who is the new and living way is replacing the old – He is the fulfillment of the Law and the countless prophecies in the Old Testament. Also, in His glorified form they saw a preview of His coming glorification and enthronement as King of kings and Lord of lords. We see here a preview of what we later read in Revelation.

The disciples never forgot what happened that day on the mountain and no doubt this was intended. John wrote in his gospel, “We have seen His glory, the glory of the one and only” (John 1:14). Peter also wrote of it, “We did not follow cleverly invented stories when we told you about the power and coming of our Lord Jesus Christ, but we were eyewitnesses of His majesty. For He received honor and glory from God the Father when the voice came to Him from the Majestic Glory, saying, ‘This is my Son, whom I love; with Him I am well pleased.’ We ourselves heard this voice that came from heaven when we were with Him on the sacred mountain” (2 Peter 1:16-18). Those who witnessed the transfiguration bore witness to it to the other disciples and to countless millions down through the centuries. The Greek word metamorphoō, which means “transfigure,” is used in the New Testament to describe three significant events: the time Jesus was completely glorified in His bodily appearance in the presence of James, Peter, and John; the time Jesus arose from the dead and was transfigured; and the time when all believers will also receive a new, transfigured body when they rise from the dead.

According to the Gospel accounts (Matt. 17:1–8; Mark 9:2–8; Luke 9:28–36; 2 Pet. 1:16–18), Jesus’ transfiguration was quite spectacular: “his face shone like the sun, and his garments became white as light” (Matt. 17:2). This transformation is described in Matthew and Mark by the Greek verb metamorphoō, the root for the word “metamorphosis.” This indicates that a tremendous change occurred.

This is indeed the Christ, the Son of God. In 2 Peter 1:16–18, Peter recounts that he was an eyewitness of the transfiguration.

John seems to have done the same thing, when he wrote the prologue to his gospel and said, “… we have beheld his glory” (John 1:14). At the transfiguration the true form (Greek, morphe) of the Son of God temporally broke through the veil of His humanity and the disciples saw His preexistent glory. In this transformation, Jesus, the three disciples witnessed something of Jesus’ pre-incarnate glory, as well as His future glory which He received at His resurrection and which all will see when He returns to judge the world.

When Christ returns in His glory, all believers will also be transfigured and thereby receive a glorious, resurrected body. Thus, Christ’s transfiguration is the preview of every believer’s own transfiguration

(1 Cor. 15:42–45; Phil. 3:20–21; Col. 3:4).

Jesus did not stay on the mountaintop.

The disciples and Jesus came off the mountain, and they came right down to the bottom of the valley. They came off the mountain and they came down into the valley and they found a boy who was having epileptic seizures. The mother and father were enormously upset and worried about the desperately sick boy, and the little boy fell into a fire and burned himself. In other words, the disciples came down off that mountaintop right into the problems of real life.

Home from a mountaintop vacation and into the real world at home. The disciples discovered that God is also down in the valley and does not live only or even primarily on the mountaintop.

You and I experience the valleys of life. You and I both know what happens the next day coming down from the mountain. It is the real world and the real life. After Sundays of life, there are always Mondays. You know, the tough ones of life. God is with us there.
