Mark 8:34-38
34 Then Jesus asked the crowd and his disciples to come to him. He said to them, ‘A person who wants to come with me must not think about himself. He must decide that his own life is not important. He must be like someone who carries his own cross to go and die. Then he may come with me as my disciple. 35 Whoever wants to keep his own life safe will lose it. But whoever gives his life to serve me and God's good news will have true life. 36 A person may get everything in the whole world for himself. But if he loses his life, it will not be any good for him. 37 There is nothing that a person can give to get back his life.
38 People who are living today do not obey God. They are very bad. But you must not be ashamed of me or of my words. If you are, then the Son of Man will be ashamed of you. One day he will return and God's holy angels will be with him. He will have the bright glory of his Father. He will be ashamed of you on that day if you are ashamed of him now.’
