"I am the true vine, and my Father is the gardener.
He cuts off every branch in me that bears no fruit,
while every branch that does bear fruit he prunes
so that it will be even more fruitful."
"I am the vine; you are the branches.
If a man remains in me and I in him, he will bear much fruit;
apart from me you can do nothing."
John 15 : 1-2, 5
