John 15:2-6

He cares for the branches connected to me by lifting and propping up the fruitless branches and pruning every fruitful branch to yield a greater harvest. The words I have spoken over you have already cleansed you. So you must remain in life-union with me, for I remain in life-union with you. For as a branch severed from the vine will not bear fruit, so your life will be fruitless unless you live your life intimately joined to mine. “I am the sprouting vine and you’re my branches. As you live in union with me as your source, fruitfulness will stream from within you—but when you live separated from me you are powerless. If a person is separated from me, he is discarded; such branches are gathered up and thrown into the fire to be burned.
