Simon has just hosted the preacher, Jesus, who had used his boat as a pulpit to address the crowds (Luke 5:1-3). The Master selected Simon's boat because, although he did not know it, Jesus wanted him to become His disciple. The word 'disciple' does not mean 'follower', as many think, but 'learner'. True learning is always practical. It is not enough for disciples to be present or to hear (like many who sit in church); it is essential that they learn what they have heard by putting the teaching into practice (Luke 14:27).
