John 15:4-5

New Revised Standard Version, Anglicised Catholic Edition

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.
