Jesus Christ said that He is real vine. Father is the person who looks after garden, gardener. We are branches. Jesus expects us to bear fruits. Father will break off every branch that does not bear fruits. He will also cut the branch so that it bears more fruits. If we want to be fruitful, we should do these.
We must remain united with God. WE must remain in the love of God. We must remain obey the great laws of God. If we are fruitful our father will get glory. Jesus Christ will be joyful. Our joy will be complete.
