John 15:4-7

4Remain in me, and I in you. Just as a branch is unable to produce fruit by itself unless it remains on the vine, neither can you unless you remain in me.

5I am the vine; you are the branches. The one who remains in me and I in him produces much fruit, because you can do nothing without me.

6If anyone does not remain in me, he is thrown aside like a branch and he withers. They gather them, throw them into the fire, and they are burned.

7If you remain in me and my words remain in you, ask whatever you want and it will be done for you.
