Luke 9:26-27

So why then are you ashamed of being my disciple? Are you ashamed of the revelation-truth I give to you? “I, the Son of Man, will one day return in my radiant brightness, with the holy angels and in the splendor and majesty of my Father. On that day I will be ashamed of everyone who has been ashamed of me. “I promise you this: there are some of you standing here right now who will not die until you have witnessed the presence and the power of God’s kingdom realm.”
