Concept of Slavery

Slavery is wrong from a "human point of view". I am sure God do not like slavery however He never forbid slavery in the Word of God. The Bible have alot of positive and negative attributes of "Slavery". We were slaves to sin as Jesus said in John 8:34 "I tell you the truth, everyone who sins is a slave to sin." Paul wrote in Romans 7:14 "We know that the law is spiritual; but I am unspiritual, sold as a slave to sin." (Romans 6:20: When you were slaves to sin, you were free from the control of righteousness.) And now we are slaves to God (Romans 6:22: But now that you have been set free from sin and have become slaves to God, the benefit you reap leads to holiness, and the result is eternal life.) Its amazing how we can "picture" slavery and we can see how bad slavery can be in negative (sin) and how good slavey can be in positive (Christ).
