John 15:6-8

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.
