They said therefore to him, "Who are you? Give us an answer to take back to those who sent us. What do you say about yourself?"
It is not something that you can set your mind to and become. That is, "I am going to live this new dynamic life. I'm not going to walk in darkness any more; I'm going to live a generous, self-sacrificing life, the life that is the ideal that God has declared for man." You can't do it by the will of the flesh.
