Thus Lucretius conceived of the absolute Being as by the necessity of its nature entirely outside our system.
But Moses was taught to trust in Jehovah as intervening, pitying sorrow and wrong, coming down to assist His creatures in distress.
How could this be possible? Clearly the movement towards them must be wholly disinterested, and wholly from within; unbought, since no external influence can modify His condition, no puny sacrifice can propitiate Him Who sitteth upon the circle of the earth and the inhabitants thereof are as grasshoppers: a movement prompted by no irregular emotional impulse, but an abiding law of His nature, incapable of change, the movement of a nature, personal indeed, yet as steady, as surely to be reckoned upon in like circumstances, as the operations of gravitation are.
There is no such motive, working in such magnificent regularity for good, save one. The ultimate doctrine of the New Testament, that God is Love, is already involved in this early assertion, that being wholly independent of us and our concerns, He is yet not indifferent to them, so that Moses could say unto the children of Israel “I am hath sent me unto you.”
It is this unchangeable consistency of Divine action which gives the narrative its intense interest to us. To Moses, and therefore to all who receive any commission from the skies, this title said, Frail creature, sport of circumstances and of tyrants, He who commissions thee sits above the waterfloods, and their rage can as little modify or change His purpose, now committed to thy charge, as the spray can quench the stars. Perplexed creature, whose best self lives only in aspiration and desire, now thou art an instrument in the hand of Him with Whom desire and attainment, will and fruition, are eternally the same. None truly fails in fighting for Jehovah, for who hath resisted His will?
To Israel, and to all the oppressed whose minds are open to receive the tidings and their faith strong to embrace it, He said, Your life is blighted, and your future is in the hand of taskmasters, yet be of good cheer, for now your deliverance is undertaken by Him Whose being and purpose are one, Who is in perfection of enjoyment all that He is in contemplation and in will. The rescue of Israel by an immutable and perfect God is the earnest of the breaking of every yoke.
And to the proud and godless world which knows Him not, He says, Resistance to My will can only show forth all its power, which is not at the mercy of opinion or interest or change: I sit upon the throne, not only supreme but independent, not only victorious but unassailable; self-contained, self-poised and self-sufficing, I am that I am.
Have we now escaped the inert and self-absorbed deity of Lucretius, only to fall into the palsying grasp of the tyrannous deity of Calvin? Does our own human will shrivel up and become powerless under the compulsion of that immutability with which we are strangely brought into contact?
Evidently this is not the teaching of the Book of Exodus. For it is here, in this revelation of the Supreme, that we first hear of a nation as being His: “I have seen the affliction of My people which is in Egypt ... and I have come down to bring them into a good land.” They were all baptized into Moses in the cloud and in the sea. Yet their carcases fell in the wilderness. And these things were written for our learning. The immutability, which suffers no shock when we enter into the covenant, remains unshaken also if we depart from the living God. The sun shines alike when we raise the curtain and when we drop it, when our chamber is illumined and when it is dark. The immutability of God is not in His operations, for sometimes He gave His people into the hand of their enemies, and again He turned and helped them. It is in His nature, His mind, in the principles which guide His actions. If He had not chastened David for his sin, then, by acting as before, He would have been other at heart than when He rejected Saul for disobedience and chose the son of Jesse to fulfil all His word. The wind has veered, if it continues to propel the vessel in the same direction, although helm and sails are shifted.
Such is the Pauline doctrine of His immutability. “If we endure we shall also reign with Him: if we shall deny Him, He also will deny us,”—and such is the necessity of His being, for we cannot sway Him with our changes: “if we are faithless, He abideth faithful, for He cannot deny Himself.” And therefore it is presently added that “the firm foundation of the Lord standeth sure, having” not only “this seal, that the Lord knoweth those that are His,”—but also this, “Let every one that nameth the name of the Lord depart from unrighteousness” (2 Tim. ii. 12, 13, 19, R.V.).
