Luke 9:26-27

26You must not be ashamed of me and of my words. If you are, then the Son of Man will be ashamed of you. One day he will return and everyone will see his power. He will come with God's holy angels and he will have the bright glory of his Father God. He will be ashamed of you on that day, if you are ashamed of him now.’

27Then Jesus said, ‘What I tell you is true. Some people who are standing here will see clearly God begin to rule in his kingdom. They will see that before they die.’
