This is not talking about repentance from sin, but from living a self-centred life at the core of our being, a life lived out of duty, obligation, legalism, my efforts to be loved, needed, valued, feel good. The life of God flows out of a vital love relationship with God. He is the centre, not us. Our identity is with him. His life flows through a life that's yielded and open, and in love with God as a father.
