"What many people fail to understand is that slavery in Biblical times was very different from the slavery that was practiced in the past few centuries in many parts of the world. The slavery in the Bible was not based exclusively on race. People were not enslaved because of their nationality or the color of their skin.
In Bible times, slavery was more of a social status. People sold themselves as slaves when they could not pay their debts or provide for their family. In New Testament times, sometimes doctors, lawyers, and even politicians were slaves of someone else. Some people actually chose to be slaves so as to have all their needs provided for by their master....
Another crucial point is that the purpose of the Bible is to point the way to salvation,
not to reform society. The Bible often approaches issues from the inside-out. If a person experiences the love, mercy, and grace of God, receiving His salvation – God will reform his soul, changing the way he thinks and acts. A person who has experienced God’s gift of salvation and freedom from the slavery of sin, as God reforms his soul, he will realize that enslaving another human being is wrong. A person who has truly experienced God’s grace will in turn be gracious towards others. That would be the Bible’s prescription for ending slavery."
Does the Bible condone slavery?
Part of the problem is that we have false ideas about what slavery was really like.
The life of a slave was not easy, but we get an exaggerated idea of the hardships of slavery from watching movies or reading historical material that is written on a popular level. Here the purpose is usually to dramatize the plight of slaves or to make some point about the evils of slavery in general, (1) but the historical reality was less dramatic. In most cases the life of a slave was not much different from the life of any lower-class worker. Those who have been in the military have experienced something like it — being legally bound to an employer and to a job that one cannot simply "quit" at will, not free to leave without permission, subject to discipline if one disobeys or is grossly negligent — all of this is familiar enough to those of us who have served in the military. And yet we know that the daily life of a good soldier is not especially hard. This is what it was like to be a slave.
Another problem is, when thinking about slavery we tend to have in mind the recent slavery of the black race in America, and so the whole subject of slavery gets mixed up with the issue of racism. But in ancient times, slavery was not associated with any particular race. By condoning slavery the Bible does not approve of racism.
A third reason why modern people have a hard time understanding the Bible's treatment of slavery is that we often now tend to confuse morality with political values. The modern tendency is to politicize everything, including even the Christian gospel. Moral philosophy or ethics has become so politicized that it seems to be almost a sub-department of political science now, which is why we have seen the rise of an elaborate political correctness in our public life. "Racism," "sexism," "homophobia," and so on, are the really serious sins under this new morality.
