If, then, Abraham was to become the founder, not of one new warlike power in addition to the already too numerous warlike powers of the East, but of a religion which should finally develop into the most elevating and purifying influence among men, it is obvious that Ishmael was not at all a desirable heir. Whatever pain it gave to Abraham to part with him, separation in some form had become necessary. It was impossible that the father should continue to enjoy the filial affection of Ishmael, his lively talk, and warm enthusiasm, and adventurous exploits, and at the same time concentrate his hope and his care on Isaac. He had, therefore, to give up, with something of the sorrow and self-control he afterwards underwent in connection with the sacrifice of Isaac, the lad whose bright face had for so many years shone in all his paths. And in some such way are we often called to part with prospects which have wrought themselves very deep into our spirit, and which, indeed, just because they are very promising and seductive, have become dangerous to us, upsetting the balance of our life, and throwing into the shade objects and purposes which ought to be outstanding. And when we are thus required to give up what we were looking to for comfort, for applause, and for profit, the voice of God in its first admonition sometimes seems to us little better than the jealousy of a woman. Like Sarah's demand, that none should share with her son, does the requirement seem which indicates to us that we must set nothing on a level with God's direct gifts to us. We refuse to see why we may not have all the pleasures and enjoyments, all the display and brilliance that the world can give. We feel as if we were needlessly restricted. But this instance shows us that when circumstances compel us to give up something of this kind which we have been cherishing, room is given for a better thing than itself to grow.
For Ishmael himself, too, wronged as he was in the mode of his expulsion, it was yet far better that he should go. Isaac _was_ the true heir. No jeering allusions to his late birth or to his appearance could alter that fact. And to a temper like Ishmael's it was impossible to occupy a subordinate, dependent position. All he required to call out his latent powers was to be thrown thus on his own resources. The daring and high spirit and quickness to take offence and use violence, which would have wrought untold mischief in a pastoral camp, were the very qualities which found fit exercise in the desert, and seemed there only in keeping with the life he had to lead. And his hard experience at first would at his age do him no harm, but good only. To be compelled to face life single-handed at the age of sixteen is by no means a fate to be pitied. It was the making of Ishmael, and is the making of many a lad in every generation.
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."
