A reminder again that in order for you to bear fruit, you must remain faithful to Jesus. The image here is that of a grape vine. In order for grapes to grow and produce good fruit the branches must be attached to the vine. In the same way in order for you grow and produce good fruit you must attach yourself to the vine of Jesus. In doing this you allow yourself to be filled with the nutrients required to produce good fruit.
