John 15:2-4

Revised Standard Version

² Every branch of mine that bears no fruit, he takes away, and every branch that does bear fruit he prunes, that it may bear more fruit. ³ You are already made clean by the word which I have spoken to you. ⁴ Abide in me, and I in you. As the branch cannot bear fruit by itself, unless it abides in the vine, neither can you, unless you abide in me.
