But our present concern is with the practical message conveyed to Israel when Moses declared that Jehovah, I AM, the God of their fathers, had appeared unto him. And if we find in it a message suited for the time, and which is the basis, not the superstructure, both of later messages and also of the national character, then we shall not fail to observe the bearing of such facts upon an urgent controversy of this time.
Some significance must have been in that Name, not too abstract for a servile and degenerate race to apprehend. Nor was it soon to pass away and be replaced; it was His memorial throughout all generations; and therefore it has a message for us to-day, to admonish and humble, to invigorate and uphold.
That God would be the same to them as to their fathers was much. But that it was of the essence of His character to be evermore the same, immutable in heart and mind and reality of being, however their conduct might modify His bearing towards them, this indeed would be a steadying and reclaiming consciousness.
Accordingly Moses receives the answer for himself, "I AM THAT I AM"; and he is bidden to tell his people "_I am_ hath sent me unto you," and yet again "JEHOVAH the God of your fathers hath sent me unto you." The spirit and tenor of these three names may be said to be virtually comprehended in the first; and they all speak of the essential and self-existent Being, unchanging and unchangeable.
I AM expresses an intense reality of being. No image in the dark recesses of Egyptian or Syrian temples, grotesque and motionless, can win the adoration of him who has had communion with such a veritable existence, or has heard His authentic message. No dreamful pantheism, on its knees to the beneficent principle expressed in one deity, to the destructive in another, or to the reproductive in a third, but all of them dependent upon nature, as the rainbow upon the cataract which it spans, can ever again satisfy the soul which is athirst for the living God, the Lord, Who is not personified, but IS.
This profound sense of a living Person within reach, to be offended, to pardon, and to bless, was the one force which kept the Hebrew nation itself alive, with a vitality unprecedented since the world began. They could crave His pardon, whatever natural retributions they had brought down upon themselves, whatever tendencies of nature they had provoked, because He was not a dead law without ears or a heart, but their merciful and gracious God.
Not the most exquisite subtleties of innuendo and irony could make good for a day the monstrous paradox that the Hebrew religion, the worship of I AM, was really nothing but the adoration of that stream of tendencies which makes for righteousness.
Israel did not challenge Pharaoh through having suddenly discovered that goodness ultimately prevails over evil, nor is it any cold calculation of the sort which ever inspires a nation or a man with heroic fortitude. But they were nerved by the announcement that they had been remembered by a God Who is neither an ideal nor a fancy, but the Reality of realities, beside Whom Pharaoh and his host were but as phantoms.
I AM THAT I AM is the style not only of permanence, but of permanence self-contained, and being a distinctive title, it denies such self-contained permanence to others.
Man is as the past has moulded him, a compound of attainments and failures, discoveries and disillusions, his eyes dim with forgotten tears, his hair grey with surmounted anxieties, his brow furrowed with bygone studies, his conscience troubled with old sin. Modern unbelief is ignobly frank respecting him. He is the sum of his parents and his wet-nurse. He is what he eats. If he drinks beer, he thinks beer. And it is the element of truth in these hideous paradoxes which makes them rankle, like an unkind construction put upon a questionable action. As the foam is what wind and tide have made of it, so are we the product of our circumstances, the resultant of a thousand forces, far indeed from being self-poised or self-contained, too often false to our best self, insomuch that probably no man is actually what in the depth of self-consciousness he feels himself to be, what moreover he should prove to be, if only the leaden weight of constraining circumstance were lifted off the spring which it flattens down to earth. Moses himself was at heart a very different person from the keeper of the sheep of Jethro. Therefore man says, Pity and make allowance for me: this is not my true self, but only what by compression, by starvation and stripes and bribery and error, I have become. Only God says, I AM THAT I AM.
