“It is not to be expected that we should love God supremely if we have not known him to be more desirable than all other things.” So wrote the great hymn writer Isaac Watts. And of course, he was quite right, for we always love what seems most attractive to us. Whether it be God, money, sex, or fame, we live for and love what captures our hearts.
But what kind of God could outstrip the attractions of all other things? Could any unitary, single-person god do so? Hardly, or at least not for long. Single-person gods must, by definition, have spent eternity in absolute solitude. Before creation, having no other persons with whom they could commune, they must have been entirely alone.
Love for others, then, cannot go very deep in them if they can go for eternity without it. And so, not being essentially loving, such gods are inevitably less than lovely. They may demand our worship, but they cannot win our hearts. They must be served with gritted teeth.
How wonderfully different it is with the triune God. In John 17:24, Jesus speaks of how the Father loved Him even before the creation of the world. That is the triune, living God: a Father, whose very being has eternally been about loving His Son, pouring out the Spirit of love and life on Him. Here is a God who is love, who is so full of life and blessing that for eternity He has been overflowing with it. As the Puritan preacher Richard Sibbes put it: “Such a goodness is in God as is in a fountain, or in the breast that loves to ease itself of milk.” Here in the triune God, in other words, is an infinitely satisfying God, one who is the very fountainhead of all goodness, truth, and beauty.
That means that with the triune God there is great good news. For here is no mean and grasping God, but a Lord of grace and mercy—one, in fact, who offers a salvation sweeter than any non-triune God could ever imagine.
Just imagine for a moment a single-person god. Having been alone for eternity, would it want fellowship with us? It seems most unlikely. Would it even know what fellowship was? Almost certainly not. Such a god might allow us to live under its rule and protection, but little more. Think of the uncertain hope of the Muslim or the Jehovah’s Witness: they may finally attain paradise, but even there they will have no real fellowship with their god. Their god would not want it.
But if God is a Father, whose very life has been about loving and delighting in His precious Son, then you begin to see a God who would have far more intimate and marvelous aims, aims to draw us into His life and joy, to embrace us with the very love He has for His dear Son.
