2 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. 3 His clothes became dazzling white, whiter than anyone in the world could bleach them. 4 And there appeared before them Elijah and Moses, who were talking with Jesus.
5 Peter said to Jesus, “Rabbi, it is good for us to be here. Let us put up three shelters—one for you, one for Moses and one for Elijah.” 6 (He did not know what to say, they were so frightened.)
7 Then a cloud appeared and covered them, and a voice came from the cloud: “This is my Son, whom I love. Listen to him!”
8 Suddenly, when they looked around, they no longer saw anyone with them except Jesus.
9 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.
The disciples knew Jesus well as a man but here they had a glimpse of his true nature – that of the Son of God which is how he will return. The most important message here is in verse 7 where the Father, Yahweh tells the disciples not only who Jesus is but also that they must listen to Him. Listening to Jesus through his Word in the Gospels is still central to true Christianity today and it is important we are not distracted from that by anyone.
