Luke 9:27

²⁵ What does it profit a man to gain the whole world, yet lose or forfeit his very self?

²⁶ If anyone is ashamed of Me and My words, the Son of Man will be ashamed of him when He comes in His glory and in the glory of the Father and of the holy angels.

But I tell you truthfully, some who are standing here will not taste death before they see the kingdom of God.”

²⁸ About eight days after Jesus had said these things, He took with Him Peter, John, and James, and went up on a mountain to pray.

²⁹ And as He was praying, the appearance of His face changed, and His clothes became radiantly white.

Do read the surrounding verses too, because the context often says more than a single verse.
