Luke 9:26-29

26For whoever is ashamed of Me and My words, of him the Son of Man will be ashamed when He comes in His own glory, and in His Father’s, and of the holy angels.

27But I tell you truly, there are some standing here who shall not taste death till they see the kingdom of God.”

28Now it came to pass, about eight days after these sayings, that He took Peter, John, and James and went up on the mountain to pray.

29As He prayed, the appearance of His face was altered, and His robe became white and glistening.
