"I am the vine; you are the branches.  If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing. ⁶ If you do not remain in me, you are like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. ⁷ If you remain in me and my words remain in you, ask whatever you wish, and it will be done for you. ⁸ This is to my Father’s glory, that you bear much fruit, showing yourselves to be my disciples."

(John 15:5-8 -- NIV)
