John 15:3-5

You are already clean because of the word I have spoken to you.

Remain in Me, and I will remain in you. Just as no branch can bear fruit by itself unless it remains in the vine, neither can you bear fruit unless you remain in Me.

I am the vine and you are the branches. The one who remains in Me, and I in him, will bear much fruit. For apart from Me you can do nothing.
