Read John 15:1-8
15 “I am the real vine, and my Father is the gardener. 2He breaks off every branch in me that does not bear fruit, and he prunes every branch that does bear fruit, so that it will be clean and bear more fruit. 3You have been made clean already by the teaching I have given you. 4Remain united to me, and I will remain united to you. A branch cannot bear fruit by itself; it can do so only if it remains in the vine. In the same way you cannot bear fruit unless you remain in me.
5 “I am the vine, and you are the branches. Those who remain in me, and I in them, will bear much fruit; for you can do nothing without me. 6Whoever does not remain in me is thrown out like a branch and dries up; such branches are gathered up and thrown into the fire, where they are burnt. 7If you remain in me and my words remain in you, then you will ask for anything you wish, and you shall have it. 8My Father’s glory is shown by your bearing much fruit; and in this way you become my disciples.
"My Father's glory is shown by your bearing much fruit; and in this way you become my disciples." - 8
In verse 1 and 2 Jesus speaks about pruning away that in our lives which does not produce fruit - in order to produce more fruit, more goodness - more of God's love in the world.
