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.
