But the two fugitives are soon reminded that, though expelled from Abraham’s tents and protection, they are not expelled from his God. Ishmael finds it true that when father and mother forsake him, the Lord takes him up. At the very outset of his desert life he is made conscious that God is still his God, mindful of his wants, responsive to his cry of distress. It was not through Ishmael the promised seed was to come, but the descendants of Ishmael had every inducement to retain faith in the God of Abraham, who listened to their father’s cry. The fact of being excluded from certain privileges did not involve that they were to be excluded from all privileges. God still “heard the voice of the lad, and the angel of God called to Hagar out of heaven.”
It is this voice of God to Hagar that so speedily, and apparently once for all, lifts her out of despair to cheerful hope. It would appear as if her despair had been needless; at least from the words addressed to her, “What aileth thee, Hagar?” it would appear as if she might herself have found the water that was close at hand, if only she had been disposed to look for it. But she had lost heart, and perhaps with her despair was mingled some resentment, not only at Sarah, but at the whole Hebrew connection, including the God of the Hebrews, who had before encouraged her. Here was the end of the magnificent promise which that God had made her before her child was born—a helpless human form gasping its life away without a drop of water to moisten the parched tongue and bring light to the glazing eyes, and with no easier couch than the burning sand. Was it for this, the bitterest drop that, apart from sin, can be given to any parent to drink, she had been brought from Egypt and led through all her past? Had her hopes been nursed by means so extraordinary only that they might be so bitterly blighted? Thus she leapt to her conclusions, and judged that because her skin of water had failed God had failed her too. No one can blame her, with her boy dying before her, and herself helpless to relieve one pang of his suffering. Hitherto in the well-furnished tents of Abraham she had been able to respond to his slightest desire. Thirst he had never known, save as the relish to some boyish adventure. But now, when his eyes appeal to her in dying anguish, she can but turn away in helpless despair. She cannot relieve his simplest want. Not for her own fate has she any tears, but to see her pride, her life and joy, perishing thus miserably, is more than she can bear.
No one can blame, but every one may learn from her. When angry resentment and unbelieving despair fill the mind, we may perish of thirst in the midst of springs. When God’s promises produce no faith, but seem to us so much waste paper, we are necessarily in danger of missing their fulfilment. When we ascribe to God the harshness and wickedness of those who represent Him in the world, we commit moral suicide. So far from the promises given to Hagar being now at the point of extinction, this was the first considerable step towards their fulfilment. When Ishmael turned his back on the familiar tents, and flung his last gibe at Sarah, he was really setting out to a far richer inheritance, so far as this world goes, than ever fell to Isaac and his sons.
But the chief use Paul makes of this entire episode in the history is to see in it an allegory, a kind of picture made up of real persons and events, representing the impossibility of law and gospel living harmoniously together, the incompatibility of a spirit of service with a spirit of sonship. Hagar, he says, is in this picture the likeness of the law given from Sinai, which gendereth to bondage. Hagar and her son, that is to say, stand for the law and the kind of righteousness produced by the law,—not superficially a bad kind; on the contrary, a righteousness with much dash and brilliance and strong manly force about it, but at the root defective, faulty in its origin, springing from the slavish spirit. And first Paul bids us notice how the free-born is persecuted and mocked by the slave-born, that is, how the children of God who are trying to live by love and faith in Christ are put to shame and made uneasy by the law. They believe they are God’s dear children, that they are loved by Him, and may go out and in freely in His house as their own home, using all that is His with the freedom of His heirs; but the law mocks them, frightens them, tells them it is God’s first-born, law lying far back in the dimness of eternity, coeval with God Himself. It tells them they are puny and weak, scarcely out of their mother’s arms, tottering, lisping creatures, doing much mischief, but none of the housework, at best only getting some little thing to pretend to work at. In contrast to their feeble, soft, unskilled weakness, it sets before them a finely-moulded, athletic form, becoming disciplined to all work, and able to take a place among the serviceable and able-bodied. But with all this there is in that puny babe a life begun which will grow and make it the true heir, dwelling in the house and possessing what it has not toiled for, while the vigorous, likely-looking lad must go into the wilderness and make a possession for himself with his own bow and spear.
Now, of course, righteousness of life and character, or perfect manhood, is the end at which all that we call salvation aims, and that which can give us the purest, ripest character is salvation for us; that which can make us, for all purposes, most serviceable and strong. And when we are confronted with persons who might speak of service we cannot render, of an upright, unfaltering carriage we cannot assume, of a general human worthiness we can make no pretension to, we are justly perturbed, and should regain our equanimity only under the influence of the most undoubted truth and fact. If we can honestly say in our hearts, “Although we can show no such work done, and no such masculine growth, yet we have a life in us which is of God, and will grow;” if we are sure that we have the spirit of God’s children, a spirit of love and dutifulness, we may take comfort from this incident. We may remind ourselves that it is not he who has at the present moment the best appearance who always abides in the father’s home, but he who is by birth the heir. Have we or have we not the spirit of the Son? not feeling that we must every evening make good our claim to another night’s lodging by showing the task we have accomplished, but being conscious that the interests in which we are called to work are our own interests, that we are heirs in the father’s house, so that all we do for the house is really done for ourselves. Do we go out and in with God, feeling no need of His commands, our own eye seeing where help is required, and our own desires being wholly directed towards that which engages all His attention and work?
For Paul would have each of us apply, allegorically, the words, Cast out the bondwoman and her son, that is, cast out the legal mode of earning a standing in God’s house, and with this legal mode cast out all the self-seeking, the servile fear of God, the self-righteousness, and the hard-heartedness it engenders. Cast out wholly from yourself the spirit of the slave, and cherish the spirit of the son and heir. The slave-born may seem for a while to have a firm footing in the father’s house, but it cannot last. The temper and tastes of Ishmael are radically different from those of Abraham, and when the slave-born becomes mature, the wild Egyptian strain will appear in his character. Moreover, he looks upon the goods of Abraham as plunder; he cannot rid himself of the feeling of an alien, and this would, at length, show itself in a want of frankness with Abraham—slowly, but surely, the confidence between them would be worn out. Nothing but being a child of God, being born of the Spirit, can give the feeling of intimacy, confidence, unity of interest, which constitutes true religion. All we do as slaves goes for nothing; that is to say, all we do, not because we see the good of it, but because we are commanded; not because we have any liking for the thing done, but because we wish to be paid for it. The day is coming when we shall attain our majority, when it will be said to us by God, Now, do whatever you like, whatever you have a mind to; no surveillance, no commands are now needed; I put all into your own hand. What, in these circumstances, should we straightway do? Should we, for the love of the thing, carry on the same work to which God’s commands had driven us; should we, if left absolutely in charge, find nothing more attractive than just to prosecute that idea of life and the world set before us by Christ? Or, should we see that we had merely been keeping ourselves in check for a while, biding our time, untamed as Ishmael, craving the rewards but not the life of the children of God? The most serious of all questions these—questions that determine the issues of our whole life, that determine whether our home is to be where all the best interests of men and the highest blessings of God have their seat, or in the pathless desert where life is an aimless wandering, dissociated from all the forward movements of men.
The distinction between the servile spirit and the spirit of sonship being thus radical, it could be by no mere formality, or exhibition of his legal title, that Isaac became the heir of God’s heritage. His sacrifice on Moriah was the requisite condition of his succession to Abraham’s place; it was the only suitable celebration of his majority. Abraham himself had been able to enter into covenant with God only by sacrifice; and sacrifice not of a dead and external kind, but vivified by an actual surrender of himself to God, and by so true a perception of God’s holiness and requirements, that he was in a horror of great darkness. By no other process can any of his heirs succeed to the inheritance. A true resignation of self, in whatever outward form this resignation may appear, is required that we may become one with God in His holy purposes and in His eternal blessedness. There could be no doubt that Abraham had found a true heir, when Isaac laid himself on the altar and steadied his heart to receive the knife. Dearer to God, and of immeasurably greater value than any service, was this surrender of himself into the hand of his Father and his God. In this was promise of all service and all loving fellowship. “Precious in the sight of the Lord is the death of His saints. O Lord, truly I am Thy servant; I am Thy servant, the son of Thine handmaid: Thou hast loosed my bonds.”
So incomparable with the most distinguished service did this sacrifice of Isaac’s self appear, that the record of his active life seems to have had no interest to his contemporaries or successors. There was but this one thing to say of him. No more seemed needful. The sacrifice was indeed great, and worthy of commemoration. No act could so conclusively have shown that Isaac was thoroughly at one with God. He had much to live for; from his birth there hovered around him interests and hopes of the most exciting and flattering nature; a new kind of glory such as had not yet been attained on earth was to be attained, or, at any rate, approached in him. This glory was certain to be realised, being guaranteed by God’s promise, so that his hopes might launch out in the boldest confidence and give him the aspect and bearing of a king; while it was uncertain in the time and manner of its realisation, so that the most attractive mystery hung around his future. Plainly his was a life worth entering on and living through; a life fit to engage and absorb a man’s whole desire, interest, and effort; a life such as might well make a man gird himself and resolve to play the man throughout, that so each part of it might reveal its secret to him, and that none of its wonder might be lost. It was a life which, above all others, seemed worth protecting from all injury and risk, and for which, no doubt, not a few of the home-born servants in the patriarchal encampment would have gladly ventured their own. There have, indeed, been few, if any, lives of which it could so truly be said, The world cannot do without this—at all hazards and costs this must be cherished. And all this must have been even more obvious to its owner than to any one else, and must have begotten in him an unquestioning assurance, that he at least had a charmed life, and would live and see good days. Yet with whatever shock the command of God came upon him, there is no word of doubt or remonstrance or rebellion. He gave his life to Him who had first given it to him. And thus yielding himself to God, he entered into the inheritance, and became worthy to stand to all time the representative heir of God, as Abraham by his faith had become the father of the faithful.
