Firstly, we need to live in a consistently close relationship with Jesus. Just as a branch draws life from its vine and a tree draws life from its soil, we cannot be fruitful without the life of Jesus flowing into us.
Secondly, we need to cooperate with God when he "prunes" us, taking good things away so that even better things can grow.
