John 15:2-11

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. If anyone does not remain in Me, he is thrown out like a [broken off] branch, and withers and dies; and they gather such branches and throw them into the fire, and they are burned. If you remain in Me and My words remain in you [that is, if we are vitally united and My message lives in your heart], ask whatever you wish and it will be done for you. My Father is glorified and honored by this, when you bear much fruit, and prove yourselves to be My [true] disciples. I have loved you just as the Father has loved Me; remain in My love [and do not doubt My love for you]. If you keep My commandments and obey My teaching, you will remain in My love, just as I have kept My Father’s commandments and remain in His love. I have told you these things so that My joy and delight may be in you, and that your joy may be made full and complete and overflowing.
