Jesus said: "Just as a branch cannot bear fruit on its own unless it remains on the vine, so neither can you unless you remain in me.
"I am the vine, you are the branches. Whoever remains in me and I in him will bear much fruit, because without me you can do nothing.
"Anyone who does not remain in me will be thrown out like a branch and wither; people will gather them and throw them into a fire and they will be burned.
"If you remain in me and my words remain in you, ask for whatever you want and it will be done for you. By this is my Father glorified, that you bear much fruit and become my disciples" (John 15:4-8).
