God indeed does not love slavery; he hates it; he will have children, not slaves; but he may keep a slave in his house a long time in the hope of waking up the poor slavish nature to aspire to the sonship which belongs to him, which is his birthright. But the slave is not to be in the house forever. The father is not bound to keep his son a slave because the foolish child prefers it. Whoever will not do what God desires of him, is a slave whom God can compel to do it, however he may bear with him. He who, knowing this, or fearing punishment, obeys God, is still a slave, but a slave who comes within hearing of the voice of his master. There are, however, far higher than he, who yet are but slaves. Those to whom God is not all in all, are slaves. They may not commit great sins; they may be trying to do right; but so long as they serve God, from duty, and do not know him as their father, the joy of their being, they are slaves—good slaves, but slaves. They are by no means so slavish as those that serve from fear, but they are slaves; and because they are but slaves, they can fulfil no righteousness, can do no duty perfectly, but must ever be trying after it warily and in pain, knowing well that if they stop trying, they are lost. They are slaves indeed, for they would be glad to be adopted by one who is their own father! Where then are the sons? I know none, I answer, who are yet utterly and entirely sons or daughters. But I do know some who are enough sons and daughters to be at war with the slave in them, who are not content to be slaves to their father.
