Luke 9:23-29

Then he said to them all: “Whoever wants to be my disciple must deny themselves and take up their cross daily and follow me. For whoever wants to save their life will lose it, but whoever loses their life for me will save it. What good is it for someone to gain the whole world, and yet lose or forfeit their very self? Whoever is ashamed of me and my words, the Son of Man will be ashamed of them when he comes in his glory and in the glory of the Father and of the holy angels. “Truly I tell you, some who are standing here will not taste death before they see the kingdom of God.” About eight days after Jesus said this, he took Peter, John and James with him and went up onto a mountain to pray. As he was praying, the appearance of his face changed, and his clothes became as bright as a flash of lightning.
