"I am the real vine, and my Father is the gardener. Every branch which is part of me but fails to bear fruit, he cuts off; and every branch that does bear fruit, he prunes, so that it may bear more fruit. Right now, because of the word which I have spoken to you, you are pruned. Stay united with me, as I will with you—for just as the branch can't put forth fruit by itself apart from the vine, so you can't bear fruit apart from me. "I am the vine and you are the branches. Those who stay united with me, and I with them, are the ones who bear much fruit; because apart from me you can't do a thing. Unless a person remains united with me, he is thrown away like a branch and dries up. Such branches are gathered and thrown into the fire, where they are burned up. "If you remain united with me, and my words with you, then ask whatever you want, and it will happen for you. This is how my Father is glorified—in your bearing much fruit; this is how you will prove to be my talmidim.
(John 15:1-8 CJB)
