John 15:4-6

4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can you, except you abide in me.

5 I am the vine, you are the branches: He that stays in me, and I in him, the same brings forth much fruit: for without me you can do nothing.

6 If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.
