Jesus was transfigured before them

Mark 9:1-13

“Truly I tell you, some who are standing here will not taste death before they see that the kingdom of God has come with power.”

After six days Jesus took Peter, James and John with him and led them up a high mountain, where they were all alone. There he was transfigured before them. His clothes became dazzling white, whiter than anyone in the world could bleach them. And there appeared before them Elijah and Moses, who were talking with Jesus.

Then a cloud appeared and covered them, and a voice came from the cloud: “This is my Son, whom I love. Listen to him!”

As they were coming down the mountain, Jesus gave them orders not to tell anyone what they had seen until the Son of Man had risen from the dead. They kept the matter to themselves, discussing what “rising from the dead” meant.

Jesus replied, “To be sure, Elijah does come first, and restores all things. Why then is it written that the Son of Man must suffer much and be rejected? But I tell you, Elijah has come, and they have done to him everything they wished, just as it is written about him.”

Why?

Elijah is the prophet and Moses is the Law, Jesus is the Son of the Lord. both are different roles for human beings. 

Peter and John were chosen to see heaven the listened to the voice of the Lord, so they have more important than the other disciples.

One more thing to prove that Jesus is the Son of the Lord.

Elijah here means the John Baptist, and Jesus mentioned that he will suffer and be rejected, and raising from the dead.

All of these words will come true and they will understand what Jesus said.

How?

Can I listen to the word of the Lord? Or I am doing what I wanted? Be aware of this!
