There were great differences between these two. Ishmael, the child of his slave: Isaac, of the wedded wife. Ishmael, the offspring of expediency: Isaac, of promise. Ishmael, wild and masterful, "the wild ass"; strongly marked in his individuality; proud, independent, swift to take an insult, swift to avenge it: Isaac, quiet and retiring, submissive and meek, willing to carry wood, to be kept in the dark, to be bound, to yield up his wells, and to let his wife govern his house. And yet all differences were wiped out in that moment of supreme sorrow; and coming from his desert fastnesses, surrounded by his wild and ruffian freebooters, Ishmael united with the other son of their common father, who had displaced him in his inheritance, and who was so great a contrast to himself; but all differences were smoothed out in that hour.
Many ancient chieftains may have been gathered by that ancient cave, to join in one last act of respect to the mighty prince who had dwelt amongst them for so long. Amid the wail of the women, and the dirge which even to this day tells of sorrow for departed worth in Eastern lands -- borne by a band of his trusted retainers, whilst a vast concourse of the camp stood wrapped in reverent silence around - -- the remains of the man who had dared to trust God at all costs, and who with pilgrim steps had traversed so many weary miles, were solemnly laid beside the dust of Sarah, his faithful wife. There, in all probability, they rest even to this day, and thence they will be raised at the coming of the King.
Out of materials which were by no means extraordinary, God built up a character with which He could hold fellowship as friend with friend; and a life which has exerted a profound influence on all after-time. It would seem as if He can raise any crop He chooses, when the soil of the heart and life are entirely surrendered to Him. Why should not we henceforth yield ourselves utterly to His divine husbandry, asking Him to fulfil in us the good pleasure of His goodness, and the work of faith with power? Only let us trust Him fully, and obey Him instantly and utterly; and as the years pass by, they shall witness results which shall bring glory to God in the highest, whilst they fill us with ceaseless praise.
