"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.”
N.B. If this applies, as it does, to a fruitless branch of the true vine, a saint not abiding in Christ, the casting into the fire and burning relate, not to him, but to the fruitless, good-for-nothing branch to which he is compared.
