Jonathan Edwards argued that it is necessary that God manifest all of his attributes. Of course, in saying this, we do not mean to say that God manifests exhaustively all His glory to his creatures, as Edwards explains. But a complete manifestation of his glory means that all of his attributes must be manifested. He explains it in his sermon God’s Sovereignty in the Salvation of Men:
It is agreeable to God’s design in the creation of the universe to exercise every attribute, and thus to manifest the glory of each of them. God’s design in the creation was to glorify himself, or to make a discovery of the essential glory of his nature. It was fit that infinite glory should shine forth; and it was God’s original design to make a manifestation of his glory, as it is. Not that it was his design to manifest all his glory to the apprehension of creatures; for it is impossible that the minds of creatures should comprehend it. But it was his design to make a true manifestation of his glory, such as should represent every attribute. If God glorified one attribute, and not another, such manifestation of his glory would be defective; and the representation would not be complete. If all God’s attributes are not manifested, the glory of none of them is manifested as it is: for the divine attributes reflect glory on one another. Thus if God’s wisdom be manifested, and not his holiness, the glory of his wisdom would not be manifested as it is; for one part of the glory of the attribute of divine wisdom is, that it is holy wisdom. So if his holiness were manifested, and not his wisdom, the glory of his holiness would not be manifested as it is; for one thing which belongs to the glory of God’s holiness is, that it is a wise holiness. So it is with respect to the attributes of mercy and justice. The glory of God’s mercy does not appear as it is, unless it is manifested as a just mercy, or as a mercy consistent with justice. And so with respect to God’s sovereignty, it reflects glory on all his other attributes. It is part of the glory of God’s mercy, that it is sovereign mercy. So all the attributes of God reflect glory on one another. The glory of one attribute cannot be manifested, as it is, without the manifestation of another. One attribute is defective without another, and therefore the manifestation will be defective. Hence it was the will of God to manifest all his attributes.
