From that time forward Jesus instructed His disciples about how He must go into Jerusalem and suffer many things at the hands of the elders, chief priests, and scribes. He told them He would be killed and be raised again on the third day. Peter began to rebuke Him and said, Far be it from thee, Lord. This shall not be. Jesus turned quickly, stopped Peter, and said, Get thee behind me, Satan. Thou art an offence to me. Thou savor not the things of God, but those of men.
Then Jesus said to His disciples, If any man will come after me, let him deny himself, take up his cross, and follow me. Whoever saves his life shall lose it. Whoever loses his life, for my sake, shall find it.
What is a man profited if he gains the whole world and loses his own soul? What can a man give in exchange for his soul? The Son of man shall come in the glory of His Father, with His angels and shall reward every man according to his works. Verily, I say unto you, there are some standing here who shall not taste death until they see the Son of man coming in His kingdom.
17 After six days Jesus took Peter, James and his brother, John up into a high mountain. Here Jesus was transfigured before them. His face shone as bright as the sun. His raiment was as white as pure light. And, behold, Moses and Elias appeared and talked with Him.
Peter then said, Lord, it is good for us to be here. If thou wilt, let us make three tabernacles; one for thee, one for Moses, and one for Elias. But, as he was speaking, a bright cloud overshadowed them. From the cloud, a voice said, This is my beloved Son in whom I am well pleased. Hear ye Him.
When the disciples heard, they fell on their faces and were afraid. Then Jesus came, touched them, and said, Arise. Be not afraid. When they looked up they saw no one but Jesus. As they came down from the mountain, Jesus charged them to tell no one what they witnessed until the Son of man had risen from the dead.
His disciples asked Him, Why, then, do the scribes say that Elias must come first? Jesus answered, Elias comes first and restores all things. But I tell you that Elias has already come. They knew him not and caused him to suffer at their hands. Likewise, the Son of man shall also suffer of them. Then the disciples understood that Jesus meant John the Baptist.
As they approached the multitude, a man came up to Jesus. Kneeling down, the man said, Lord, have mercy on my son. He is lunatic and greatly vexed. He often falls into the fire and into the water. I brought my son to thy disciples but they could not cure him.
Jesus said, O faithless and perverse generation, how long shall I be with you? How long shall I suffer you? Bring the boy here to me. When Jesus rebuked the devil, he departed out of the child and the boy was cured from that very hour.
The disciples took Jesus aside and asked, Why could we not cast the devil out? Jesus answered, Because of your unbelief. Verily, I say unto you, if ye have the faith of a grain of mustard seed, ye shall say to this mountain, Move yonder and it shall move. Nothing shall be impossible. This kind of devil goes out only after much strengthening of faith by prayer and fasting.
