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.
