I am the vine, you are the branches. Those who abide in me and I in them bear much fruit, because apart from me you can do nothing. (NRSVCE John 15:5,8)
Jesus told his disciples a parable, “Can a blind person guide a blind person? Will not both fall into a pit? No disciple is superior to the teacher; but when fully trained, every disciple will be like his teacher.” Luke 6:39–40
