“The highest angel has nothing of its own that it can offer unto God, no more light, love, purity, perfection, and glorious hallelujahs, that spring from itself, or its own powers, than the poorest creature upon earth.”

¶ 8 - 9.
An Humble, Earnest and Affectionate Address to the Clergy (1761)
Context: God could not make the creature to be great and glorious in itself; this is as impossible, as for God to create beings into a state of independence on himself. "The heavens," saith David, "declare the glory of God"; and no creature, any more than the heavens, can declare any other glory but that of God. And as well might it be said, that the firmament shows forth its own handiwork, as that a holy divine or heavenly creature shows forth its own natural power.
But now, if all that is divine, great, glorious, and happy, in the spirits, tempers, operations, and enjoyments of the creature, is only so much of the greatness, glory, majesty, and blessedness of God, dwelling in it, and giving forth various births of his own triune life, light, and love, in and through the manifold forms and capacities of the creature to receive them, then we may infallibly see the true ground and nature of all true religion, and when and how we may be said to fulfill all our religious duty to God. For the creature's true religion, is its rendering to God all that is God's, it is its true continual acknowledging all that which it is, and has, and enjoys, in and from God. This is the one true religion of all intelligent creatures, whether in heaven, or on earth; for as they all have but one and the same relation to God, so though ever so different in their several births, states or offices, they all have but one and the same true religion, or right behavior towards God. Now the one relation, which is the ground of all true religion, and is one and the same between God and all intelligent creatures, is this, it is a total unalterable dependence upon God, an immediate continual receiving of every kind, and degree of goodness, blessing and happiness, that ever was, or can be found in them, from God alone. The highest angel has nothing of its own that it can offer unto God, no more light, love, purity, perfection, and glorious hallelujahs, that spring from itself, or its own powers, than the poorest creature upon earth. Could the angel see a spark of wisdom, goodness, or excellence, as coming from, or belonging to itself, its place in heaven would be lost, as sure as Lucifer lost his. But they are ever abiding flames of pure love, always ascending up to and uniting with God, for this reason, because the wisdom, the power, the glory, the majesty, the love, and goodness of God alone, is all that they see, and feel, and know, either within or without themselves. Songs of praise to their heavenly Father are their ravishing delight, because they see, and know, and feel, that it is the breath and Spirit of their heavenly Father that sings and rejoices in them. Their adoration in spirit and in truth never ceases, because they never cease to acknowledge the ALL of God; the ALL of God in the whole creation. This is the one religion of heaven, and nothing else is the truth of religion on earth.
