Verily I say unto you, there are some of them that stand here, who shall in no wise taste of death, till they see the Son of man coming in his kingdom. And after six days Jesus taketh with him Peter, and James, and John his brother, and bringeth them up into a high mountain apart: and he was transfigured before them; and his face did shine as the sun, and his garments became white as the light. And behold, there appeared unto them Moses and Elijah talking with him. And Peter answered, and said unto Jesus, Lord, it is good for us to be here: if thou wilt, I will make here three tabernacles; one for thee, and one for Moses, and one for Elijah. While he was yet speaking, behold, a bright cloud overshadowed them: and behold, a voice out of the cloud, saying, This is my beloved Son, in whom I am well pleased; hear ye him. And when the disciples heard it, they fell on their face, and were sore afraid. And Jesus came and touched them and said, Arise, and be not afraid. And lifting up their eyes, they saw no one, save Jesus only. And as they were coming down from the mountain, Jesus commanded them, saying, Tell the vision to no man, until the Son of man be risen from the dead. And his disciples asked him, saying, Why then say the scribes that Elijah must first come? And he answered and said, Elijah indeed cometh, and shall restore all things: but I say into you, that Elijah is come already, and they knew him not, but did unto him whatsoever they would. Even so shall the Son of man also suffer of them. Then understood the disciples that he spake unto them of John the Baptist.
Jesus told him, "I am the way, the truth, and the life. No one can come to the Father except through me." (John 14:6)
