Luke 9:23-29

And He was saying to them all, “If anyone wishes to come after Me, he must deny himself, and take up his cross daily and follow Me. For whoever wishes to save his life will lose it, but whoever loses his life for My sake, he is the one who will save it. For what is a man profited if he gains the whole world, and loses or forfeits himself? For whoever is ashamed of Me and My words, the Son of Man will be ashamed of him when He comes in His glory, and the glory of the Father and of the holy angels. But I say to you truthfully, there are some of those standing here who will not taste death until they see the kingdom of God.” Some eight days after these sayings, He took along Peter and John and James, and went up on the mountain to pray. And while He was praying, the appearance of His face became different, and His clothing became white and gleaming.
