You are cleansed and pruned already, because of the word which I have given you [the teachings I have discussed with you]. Dwell in Me, and I will dwell in you. [Live in Me, and I will live in you.] Just as no branch can bear fruit of itself without abiding in (being vitally united to) the vine, neither can you bear fruit unless you abide in Me.
I am the Vine; you are the branches. Whoever lives in Me and I in him bears much (abundant) fruit. However, apart from Me [cut off from vital union with Me] you can do nothing. John 15:1-5.
