John 15:1-5

“ I am the true Vine, and My Father is the vinedresser. Every branch in Me that does not bear fruit, He takes away; and every branch that continues to bear fruit, He [repeatedly] prunes, so that it will bear more fruit [even richer and finer fruit]. You are already clean because of the word which I have given you [the teachings which I have discussed with you]. Remain in Me, and I [will remain] in you. Just as no branch can bear fruit by itself without remaining in the vine, neither can you [bear fruit, producing evidence of your faith] unless you remain in Me. I am the Vine; you are the branches. The one who remains in Me and I in him bears much fruit, for [otherwise] apart from Me [that is, cut off from vital union with Me] you can do nothing.
