Seeing clearly

Seeing clearly is evidently a Christian method for being a mature disciple given today’s gospel reading at Mass (Lk 6:39ff). The images of disciple/teacher revolve around the notion of discipline? What might the New Testament mean with regard to discipline? It means that we have good energy, stability, focus, appreciation for learning, training, the ability to center on wonder and awe, and the capacity of listening. Discipline also means that you test, verify and assent to objective truth.
