Only God is Good by William Law
A religious faith that is uninspired, a hope, or love that proceeds not from the immediate working of the divine nature within us, can no more do any divine good to our souls, or unite them with the goodness of God, than an hunger after earthly food can feed us with the immortal bread of heaven. All that the natural or uninspired man does, or can do in the church, has no more of the truth or power of divine worship in it, than that which he does in the field, or shop, through a desire of riches. And the reason is, because all the acts of the natural man, whether relating to matters of religion or the world, must be equally selfish, and there is no possibility of their being otherwise. For self-love, self- esteem, self-seeking, and living wholly to self, are as strictly the whole of all that is or possibly can be in the natural man, as in the natural beast; the one can no more be better, or act above this nature, than the other. Neither can any creature be in a better, or higher state than this, till something supernatural is found in it; and this supernatural something, called in scripture the WORD, or SPIRIT, or INSPIRATION of God, is that alone from which man can have the first good thought about God, or the least power of having more heavenly desires in his spirit, than he has in his flesh.
