God is the Love that satisfies our wishes, our emotional wants; he is himself the realised wish of the heart, the wish exalted to the certainty of its fulfilment, of its reality, to that undoubting certainty before which no contradiction of the understanding, no difficulty of experience or of the external world, maintains its ground. Certainty is the highest power for man; that which is certain to him is the essential, the divine. "God is love:" this, the supreme dictum of Christianity, only expresses the certainty which human feeling has of itself, as the alone essential, i.e., absolute divine power, the certainty that the inmost wishes of the heart have objective validity and reality, that there are no limits, no positive obstacles to human feeling, that the whole world, with all its pomp and glory, is nothing weighed against human feeling. God is love: that is, feeling is the God of man, nay, God absolutely, the Absolute Being. God is the nature of human feeling, unlimited, pure feeling, made objective. God is the optative of the human heart transformed into the tempus finitum, the certain, blissful "IS,"--the unrestricted omnipotence of feeling, prayer hearing itself, feeling perceiving itself, the echo of our cry of anguish. Pain must give itself utterance; involuntarily the artist seizes the lute that he may breathe out his sufferings in its tones. He soothes his sorrow by making it audible to himself, by making it objective; he lightens the burden which weighs upon his heart by communicating it to the air, by making his sorrow a general existence. But nature listens not to the plaints of man, it is callous to his sorrows. Hence man turns away from Nature, from all visible objects. He turns within, that here, sheltered and hidden from the inexorable powers, he may find audience for his griefs. Here he utters his oppressive secrets; here he gives vent to his stifled sighs. This open-air of the heart, this outspoken secret, this uttered sorrow of the soul, is God. God is a tear of love, shed in the deepest concealment over human misery. "God is an unutterable sigh, lying in the depths of the heart;" [93] this saying is the most remarkable, the profoundest, truest expression of Christian mysticism. The ultimate essence of religion is revealed by the simplest act of religion--prayer; an act which implies at least as much as the dogma of the Incarnation, although religious speculation stands amazed at this, as the greatest of mysteries. Not, certainly, the prayer before and after meals, the ritual of animal egoism, but the prayer pregnant with sorrow, the prayer of disconsolate love, the prayer which expresses the power of the heart that crushes man to the ground, the prayer which begins in despair and ends in rapture.
