John 15:1-5
1“I am the true vine, and My Father is the keeper of the vineyard. 2He cuts off every branch in Me that bears no fruit, and every branch that does bear fruit, He prunes to make it even more fruitful. 3You are already clean because of the word I have spoken to you. 4Remain in Me, and I will remain in you. Just as no branch can bear fruit by itself unless it remains in the vine, neither can you bear fruit unless you remain in Me. 5I am the vine and you are the branches. The one who remains in Me, and I in him, will bear much fruit. For apart from Me you can do nothing.
