John 15:3-5

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

Remain in me, and I in you. As the branch can’t bear fruit by itself, unless it remains in the vine, so neither can you, unless you remain in me.

I am the vine. You are the branches. He who remains in me, and I in him, the same bears much fruit, for apart from me you can do nothing.
