In the classic fantasy book by J.R.R. Tolkien, The Hobbit, Bilbo Baggins and his troupe is traveling through a dark, dangerous forest infested with gigantic, poisonous spiders and all manner of dark critters and creepy-crawly things. Just being in that kind of place was a frightening experience. And each member of the group, especially Bilbo Baggins, wanted to get out of that dreadful forest of darkness. As they traveled on, hoping against hope that the edge of the dangerous forest was near and not having their hopes fulfilled, one of the leaders orders Bilbo Baggins to climb the tallest tree he can find in order to have a look around and see where the dark forest ended.
Reluctantly, Bilbo climbs the tree, with limbs, branches and leaves scratching at him all the way. Several times he nearly falls. Having pushed his way through the forest canopy, he is nearly blinded by the sudden and intense sunlight. It took some time for his eyes to adjust, but once they had, Bilbo found that it was very wonderful and beautiful up there. The canopy above him was the most beautiful blue sky and around him was an ocean of green tree tops. After being in the damp darkness below, he enjoyed the sunshine and was able to soak it into his weary, tired and aching bones. The fresh air blew softly in his face and invigorated his lungs and cleared his mind. What a wonderful place to be! And no doubt, if we could have asked Tolkien's fictional character, Bilbo Baggins, he would have said, "Yes, 'tis good to be here."
Now, that story is fiction, but it reminds us of a time when three disciples were permitted a view that was extraordinary. What happened on the Day of Transfiguration was real. When Jesus took Peter, James and John with Him, He took them out of the dark valleys of this world and up to a high place, a mountaintop, where their eyes would squint at the bright light of the Son of God, who would be transformed before their wondering eyes. It was good that they were there to view this special revelation of God.
