John 15:6

John 15:6. If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.

That is all that can be done with fruitless vine-branches. You cannot make anything of them. Other trees yield timber, and are useful for various purposes; but, with the vine, it is as the prophet Ezekiel says, "Son of man, What is the vine tree more than any tree, or than a branch which is among the trees of the forest? Shall wood be taken thereof to do any work? or will men take a pin of it to hang any vessel thereon? Behold, it is cast into the fire for fuel; the fire devoureth both the ends of it, and the midst of it is burned. Is it meet for any work?" It is useless if it is fruitless; and so is it with us, if we do not bear fruit unto God, we are of no service to him whatsoever.
