The Bible does NOT condone slavery but recognizes slavery as part of the social structure of the times. Rather than attacking slavery directly, biblical guidelines weakened and undermined the institution from the inside by reminding Christian masters that they had a Master and were to treat slaves as brothers (Ephesians 6:9). For slaves, the dignity that came with freedom in Christ had a powerful long-term social effect. Today we condemn slavery as inhuman and unjustifiable. But we forget or refuse to confront the many forms of slavelike servitude that we still impose on others to secure our own economic advantage. In these cases, too, the Bible urges treatment centered on human care, not greed. In the final analysis, more money in your happiness. Your approval as a Christian worker has everything to do with loving others as Jesus would.
EPHESIANS 6:9- And, ye masters, do the same things unto them, forbearing threating: knowing that your Mater also is in heaven; neither is there respect of persons with him.
