John 15:2-4

New Catholic Bible

² He removes every branch
that does not bear fruit,
and every branch that does
he prunes to make it bear even more.
³ You have already been cleansed
by the word I have spoken to you.
⁴ “Abide in me,
as I abide in you.
Just as a branch cannot bear fruit by itself
unless it abides in the vine,
so you cannot bear fruit
unless you abide in me.
