Mark 8:34-35

34Then 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.

35Whoever 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.
