There Can Be No God Without Love

God, considered as the Infinite, or I AM, sustains a fixed and necessary relation to everything which is. His relation to space is realized and fulfilled in his omnipresence. His relation to duration finds its expression and fulfillment in his eternity. His relation, as an infinite and perfect being to objects of knowledge, is realized and fulfilled in his omniscience. His relation to percipient and sentient beings, to all beings that are susceptible of happiness, is corresponded to and completed by his love; or, what is the same thing, by his desire of their happiness. So that it may be said, that he is present to and envelopes time by his eternity, space by his omnipresence, all things knowable by his omniscience, and all percipient and sentient existences by his LOVE. And as there can be no God without eternity, no God without omniscience and omnipresence, so, still more truly and emphatically, there can be no God without love. Take  away  love, and then, in distinction from the infinity of his natural existence, nothing which constitutes God, remains; nothing to give birth to happy existences, nothing to protect them and to secure their happiness, nothing to give them confidence, nothing lovely, and nothing to be loved. Take away love from the divine nature, and what would remain would be either an infinite indifferent being, or an infinite Satan.

God Is Love

We must understand what God's love is, before we can understand the union of God and man in love. And in doing this our attention is first arrested by the declaration of the Scriptures, — a declaration which is worthy of the particular notice of Christians,— that "God is love." It would be difficult to find a parallel form of expression. It is not anywhere said of God, so far as we recollect, that he is omniscience, or that he is omnipresence. It is true that the attributes of omniscience and omnipresence are essential to him as an infinite existence; but it should always be remembered that God is something more than infinity. There must be something beyond and above infinity, which shall baptize it with the character of goodness; otherwise there is no God. "God is Love."

God is love by essence.  That is to say, love is forever and unchangeably essential to his existence  as God. He was not at first, as some may be led to suppose, a mere percipient being, having all knowledge, who formed conjecturally an idea of love, came to the conclusion that it was a good and desirable thing, and then added it as an accessory to his original existence. On the contrary, God always had a heart; always had a true and effective sensibility, operating, by an eternal law of action, in the line of right and goodness. And if, by universal consent, the heart takes the precedence of the head, — if no greatness of intellect can elevate and save a man who has evil and depraved affections, — then God cannot be what he is, the infinitely desirable and infinitely good, without love as the central and leading element, the basis and the completion of his character.
