John 15:4-8

Remain in Me, and I in you. Just as a branch is unable to produce fruit by itself unless it remains on the vine, so neither can you unless you remain in Me. “I am the vine; you are the branches. The one who remains in Me and I in him produces much fruit, because you can do nothing without Me. If anyone does not remain in Me, he is thrown aside like a branch and he withers. They gather them, throw them into the fire, and they are burned. If you remain in Me and My words remain in you, ask whatever you want and it will be done for you. My Father is glorified by this: that you produce much fruit and prove to be My disciples.
