After six days Jesus took Peter, James, and his brother John, and led them up on a high mountain by themselves.
He was transformed in front of them, and His face shone like the sun. Even His clothes became as white as the light.
Suddenly, Moses and Elijah appeared to them, talking with Him.
Then Peter said to Jesus, "Lord, it's good for us to be here! If You want, I will make three tabernacles here: one for You, one for Moses, and one for Elijah."
While he was still speaking, suddenly a bright cloud covered them, and a voice from the cloud said: This is My beloved Son. I take delight in Him. Listen to Him!
When the disciples heard it, they fell facedown and were terrified.
Then Jesus came up, touched them, and said, "Get up; don't be afraid."
When they looked up they saw no one except Him-Jesus alone.
As they were coming down from the mountain, Jesus commanded them, "Don't tell anyone about the vision until the Son of Man is raised from the dead."
So the disciples questioned Him, "Why then do the scribes say that Elijah must come first?"
"Elijah is coming and will restore everything," He replied.
"But I tell you: Elijah has already come, and they didn't recognize him. On the contrary, they did whatever they pleased to him. In the same way the Son of Man is going to suffer at their hands."
Then the disciples understood that He spoke to them about John the Baptist.
When they reached the crowd, a man approached and knelt down before Him.
"Lord," he said, "have mercy on my son, because he has seizures and suffers severely. He often falls into the fire and often into the water.
I brought him to Your disciples, but they couldn't heal him."
Jesus replied, "You unbelieving and rebellious generation! How long will I be with you? How long must I put up with you? Bring him here to Me."
Then Jesus rebuked the demon, and it came out of him, and from that moment the boy was healed.
Then the disciples approached Jesus privately and said, "Why couldn't we drive it out?"
"Because of your little faith," He told them. "For I assure you: If you have faith the size of a mustard seed, you will tell this mountain, 'Move from here to there,' and it will move. Nothing will be impossible for you. [
