John 15:3-5

New Revised Standard Version, Anglicised Catholic Edition

³ You have already been cleansed^[a] by the word that I have spoken to you. ⁴ Abide in me as I abide in you. Just as the branch cannot bear fruit by itself unless it abides in the vine, neither can you unless you abide in me. ⁵ I am the vine, you are the branches. Those who abide in me and I in them bear much fruit, because apart from me you can do nothing.
