John 15:5-8

5 I am the vine. You are the branches. He who remains in me, and I in him, the same bears much fruit, for apart from me you can do nothing.  6 If a man doesn't remain in me, he is thrown out as a branch, and is withered; and they gather them, throw them into the fire, and they are burned.  7 If you remain in me, and my words remain in you, you will ask whatever you desire, and it will be done for you.

8 “In this is my Father glorified, that you bear much fruit; and so you will be my disciples.
