An apprentice is one who becomes like his or her teacher.  A disciple is not merely a person trying to learn and remember all that the Master says.  His goal is to be an apprentice who puts these teachings into practice in his own life, so that over time he will be just like the Master.  There will be trial and error.  There will be times that both he and the Master will know that he got it wrong.  Then there is another day to get it right under the tutoring of our Lord.

“A pupil is not above his teacher; but everyone, after he has been fully trained, will be like his teacher.” Luke 6:40
