John 15:1-7.

I am the true vine: and my Father is the husbandman. Every branch in me that beareth not fruit, he will take away: and every one that beareth fruit, he will purge it, that it may bring forth more fruit. Now you are clean, by reason of the word which I have spoken to you. Abide in me: and I in you. As the branch cannot bear fruit of itself, unless it abide in the vine, so neither can you, unless you abide in me. I am the vine: you the branches. He that abideth in me, and I in him, the same beareth much fruit: for without me you can do nothing. If any one abide not in me, he shall be cast forth as a branch and shall wither: and they shall gather him up and cast him into the fire: and he burneth. If you abide in me and my words abide in you, you shall ask whatever you will: and it shall be done unto you.
