John 15:2-5

15:2 He takes away every branch that does not bear fruit in me. He prunes every branch that bears fruit so that it will bear more fruit. 15:3 You are clean already because of the word that I have spoken to you. 15:4 Remain in me, and I will remain in you. Just as the branch cannot bear fruit by itself, unless it remains in the vine, so neither can you unless you remain in me.

15:5 “I am the vine; you are the branches. The one who remains in me – and I in him – bears much fruit, because apart from me you can accomplish nothing.
